Bartow-Pell Mansion

Originally inhabited by the Lenape since ca 1,000 A.D., Lenapehoking was acquired in 1654 by Connecticut physician Thomas Pell through treaty with five Lenni Lenape Sachem: Shawan Orochquot, Poquorum, Annoke, Wawhamkus and Mehumow that included 50,000 acres of what is today the Bronx and lower Westchester County. The property was passed briefly to the LeRoy family before Robert Bartow, a Pell descendant, and his wife, Maria Lorillard, purchased a portion in 1836 and completed the mansion by 1842. The Bartow family remained there until 1888, when the city of New York purchased the property along with many other acres that now make up Pelham Bay Park. In 1914, the city leased the site to the International Garden Club (ICG). The club hired the architectural firm Delano & Aldrich to restore the mansion and design the formal garden. The building opened as a museum in 1946, and in 2008 the ICG was renamed Bartow-Pell Conservancy.

The Treaty Oak
The tree under which Thomas Pell signed a land agreement with Chief Wampage and the Siwanoy Indians in 1654. With this agreement, Pell purchased a vast area including much of present day Bronx and Westchester. Although the tree has long since passed, the iron fence that surrounded it is still visible in the park.

The Bartow-Pell estate’s long history began in 1654, when Thomas Pell, an English physician from Connecticut, at the urging of the English government, bought about 50,000 acres from the native Lenape people. In 1666, King Charles II chartered the Manor of Pelham, an area that included the present-day towns of Pelham and much of what is now southern Westchester County. Thomas Pell was consigned the land grant and may have begun to build a house on the property on what was then Pelham Bay, an offshoot of Long Island Sound. His heir and nephew, Sir John Pell, completed the house after 1670. It served four generations of Pells before it burned down during the American Revolution.

The estate, which was made up of 220 acres by the end of the war, was sold to Herman and Hannah Leroy in 1813, but it was restored to the family when it was purchased in 1836 by a Pell descendant, the publisher Robert Bartow. The present gray stone Greek Revival mansion was built by Bartow on the site; he moved in with his wife and children in 1842. The house remained in the Bartow family until 1888, when the estate was acquired by New York City along with many acres of what is now Pelham Bay Park.

The mansion was rented out for some years; beginning in 1904 it served for a decade as the Day Home and School for Crippled Children. During this time, however, the buildings and gardens deteriorated, as did several other notable mansions in the park. In the mid-1930s, when Robert Moses developed Orchard Beach in Pelham Bay Park, he determined that the mansions in the park be demolished. The Bartow house escaped that fate, however, because in 1914, the city had leased the property to the International Garden Club, which was formed to promote horticultural knowledge and agreed to restore the property for use as its clubhouse and gardens. The club hired the architectural firm of Delano & Aldrich, which restored the building and designed a formal garden that was completed in 1916. This was one of the earliest restorations in the country, predating that of Monticello in 1923.

By the 1940s, the club’s fortunes had begun to dwindle, thanks to the Great Depression and World War II, and it was decided to change the club to an association for the preservation of Bartow Mansion. The building was closed for three years and reopened in November 1945 as the Bartow Mansion Museum, which was open to the public. Interior restoration, acquisition of appropriate furnishings (often loaned by other museums), and a new partnership with the Parks Department, enabled the building to become the historic house it is today. In 1959 the name Pell was added to the name of the museum, and in 2008, the International Garden Club became the Bartow-Pell Conservancy.

The house and grounds, which include formal terraces, a fountain, herb and perennial gardens, as well as an 1840s stone carriage house, are owned by the city of New York and operated by the Bartow-Pell Conservancy. The mansion is a member of the Historic House Trust, has been designated a national and a New York City landmark, and is on the National Register of Historic Places.

The portrait of Mrs. Charles Frederick Hoffman (née Zelia Krumbhaar Preston, 1867–1929) by the British artist Sydney Percy Kendrick (1874–1955) projects the calm intelligence, sophistication, and vision that befit the sitter. Prominent in New York, Newport, and English society, Zelia Hoffman left a legacy that includes the International Garden Club and the preservation of the Bartow Mansion. Enthusiastic about the exchange of American and European horticulture, in 1914 she was a founder of the International Garden Club, and president from 1914 to 1921. Under her leadership, the club leased the Bartow Mansion from New York City for use as its headquarters and began the restoration of the house and gardens. She was also a founder and president of the Newport Garden Club, and her gardens at Newport and at Norfolk, England, were famous.

The portrait was painted posthumously from a photograph in Kendrick’s London studio. A figure, genre, and landscape painter active during the early modern period, Kendrick was also a painter of fashionable portraits. Born in London, he studied art in Paris and exhibited at the Royal Academy and in the provinces. The painting, with its simple dark background and sense of formality, is a perfect foil for Zelia Hoffman and is characteristic of the artist’s grand manner portraiture.

The Treaty Oak
Thomas Pell’s Treaty Oak may be the only tree to have merited an newspaper obituary in the New York newspaper, The Sun. The article appeared on April 9, 1906, and announced the death of the giant white oak. Until then, the tree had stood for years on the grounds of the Bartow Mansion on Shore Road in Pelham Bay Park. Tradition holds that beneath its limbs more than 250 earlier, Thomas Pell had signed a treaty with the Lenape people, who had inhabited the land for hundreds of years, and acquired about 50,000 acres, including what we know today as Pelham, New Rochelle, parts of Bronx County, and much of the land east of the Hutchinson River north to Mamaroneck.

Thomas Pell Versus the Dutch
Thomas Pell of Fairfield, Connecticut was among the earliest Englishmen to establish settlements in today’s lower Westchester County. He traveled from Fairfield in 1654 to sign the treaty with Siwanoy sachems only eleven years after the Siwanoys massacred another famous settler, Anne Hutchinson, along with most of her family.

Pell’s successful negotiation of the treaty for the purchase of what came to be known as the “Lordshipp & Mannour of Pelham” had enormous implications for the dispute between the English and the Dutch over control of the area. The tract was huge. The Dutch claimed some of it. Effective control of the lands could block any further northward movement of Dutch settlers – at least along the shore of the Long Island Sound westward to the Hutchinson River.

The enormity of Pell’s move was not lost on Dutch authorities. They confronted the English settlers who arrived in the area, although they were unsuccessful in their efforts to stop the English from settling here.

Ultimately, the strength and resolve of Pell and the English settlers were fruitful. The Dutch, facing a war with England they knew they could not win, surrendered New Amsterdam to the English on September 8, 1664. New Netherland, including Westchester, passed out of the hands of the Dutch. On October 6, 1666, Thomas Pell’s rightful ownership of virtually all the land transferred by the Siwanoys in the 1654 treaty was confirmed by royal patent, signed and sealed by Governor Richard Nicolls.

Pell’s Treaty With the Siwanoys
Most historical accounts say the Treaty was signed beneath a “Treaty Oak” on November 14, 1654. It appears from a contemporary handwritten copy of the Treaty, however, that it was signed on June 27, 1654. On that date, Thomas Pell and a small band of Englishmen reportedly gathered beneath a giant oak tree along with a Siwanoy named Anhõõke, also said by some to be known as Wampage, and four other Siwanoy Indians who have been described as “sub-chieftains”. Wampage is widely believed to have been the murderer of Anne Hutchinson.

The whereabouts of the original Treaty are not known. Fortunately, though, a copy exists in what is said to be Thomas Pell’s own handwriting. He reportedly created it and forwarded it to relatives in England from whom it has been retrieved and documented.

There is no record of the price Thomas Pell paid for the land. His copy of the Treaty says only that the sellers received “trou valew & just Satisfaction” for the land. Westchester Historian Thomas Scharf, however, reported in 1886 that the “Indians received, it is said, as an equivalent for their deed of the land, sundry hogshead of Jamaica rum.” Thomas Pell reportedly took symbolic possession of his estate “by burying his seal with his arms at the root of the oak”.

A Fiery Death
For 250 years the tree beneath which, it was said, the Treaty was signed flourished. Then, on April 8, 1906, disaster struck. The Treaty Oak died a fiery death. It appears that the fire began either with a discarded cigarette or cigar and perhaps was started by a group of small boys playing near the tree. A news account that appeared on the front page of The New York Times the following day described the death of the tree as follows:

The historic Pell Oak, a fine old tree eighty feet high, at the junction of the New Rochelle and Prospect Hill Roads, under which Lord Pell stood when he signed a treaty with the Indians early in the eighteenth [sic] century, for the property now comprising the northeastern section of the Bronx, was destroyed by fire early yesterday morning.

Several years ago the Park Commission had a fence put around the tree, which began to show signs of decay, in order to make it last as long as possible. Recently a pile of dead leaves and brush accumulated within the fence, and it is supposed that some one threw a lighted cigar or cigarette there, starting the blaze. Before any one could put the fire out the flames spread to the tree and burned it to a blackened stump.

A landscape report subsequently prepared on behalf of The Bartow-Pell Mansion Museum described the demise of the tree somewhat differently, though not necessarily inconsistently. It says: “in 1906 some young boys started a fire which swept up into the trunk, effectively ending its life.” The fire was tragic. But, it seems, the tree had been dying for years.

One account, published in 1909, noted that twenty years previously the tree was eighty feet tall and quite majestic. Ten years after that, according to the same account, the state of the tree had deteriorated precipitously: “its once proud height shorn to about twelve feet above the ground, yet still covered with second growth branches of luxuriant beauty, and the stout old trunk still offering a sturdy defiance to the ravages of time and the elements.”

The last years of the legendary oak were described in another account as follows:

Sometime prior to 1902 the tree was broken in two by a storm, yet, despite a hollow trunk, it continued to thrive. In 1906 some young boys started a fire which swept up into the trunk, effectively ending its life. The following March the dead tree was blown over in a wind storm, leaving a small stump contained within the iron fence which survived for a few years… Once the gust of wind blew over the dead tree, the sad remnant of Thomas Pell’s Treaty Oak lay decaying on the ground “having crashed its way through the iron railing” built to protect it.

Death destroyed neither the legend nor the symbolism of what was known as “Thomas Pell’s Treaty Oak”. On May 1, 1915, the Governor of New York reportedly attended ceremonies during the formal opening of the Bartow-Pell Mansion as the clubhouse of the International Garden Club and planted a red oak near the site where the tree had once stood to honor Thomas Pell’s Treaty Oak and all that it had come to symbolize.

Remnants of the Oak
Thomas Pell’s Treaty Oak lives on, so to speak, in another way. Pieces of what are said to be the venerable old oak are scattered among the collections of local historical societies in homage to the tree and what it came to symbolize.

For example, the collection of the Bartow-Pell Mansion Museum includes a piece of the Pell Treaty Oak. It is about eight inches long and is encased within a glass-enclosed oval shadow box. Wire holds it in place and it rests on a hand-lettered paper affixed to the interior of the shadow box that reads in part:

The Pell Tree
That once stood within the circular fence on the Bartow Estate (Now included in Pelham Bay Park, New York)

The Pell Treaty Oak Site Today
Most of the circular, eight-and-a-half foot high iron fence that surrounded Thomas Pell’s Treaty Oak in its final years still stands more than a century after it was first built. It was erected as a “safeguard against the depredations of relic hunters” who doubtless contributed in some measure to the rapid deterioration of the oak in 1903.

As you turn from Shore Road in Pelham Bay Park through the stone-columned gate and enter the Bartow-Pell estate, look into the wooded area to your right. There, about thirty yards from the roadway amidst the trees and shrubbery, is what remains of the circular fence where the Treaty Oak stood.

Fact or Fiction?
Was the oak on the Bartow-Pell Estate that burned in 1906 the actual tree beneath which the Siwanoys granted their lands to Thomas Pell in 1654? No one knows. Biologically, it would seem possible. White oaks remain among the most abundant oaks in the eastern United States and have been known to “live to great age, over 1000 years in some cases” and to reach heights of up to 107 feet.

Certainly tradition holds that the tree that burned in 1906 was the tree that in fact spread its branches above the band that signed the Treaty on that solemn occasion. Odd references in the 1881 revised edition of Robert Bolton’s History of Westchester, and in Thomas Scharf’s 1886 History of Westchester, however, suggest otherwise. The former says the oak “formerly stood a little to the westward of” the Bartow-Pell mansion. The latter says the tree “stood until within twenty or thirty years past on the Bartow estate.”

Such passages suggest their authors believed the tree no longer stood at the time of their publication. One possibility is that the passages were mere lapses of unintended ambiguity in each of the two-volume histories of Westchester County. Sadly, that may be wishful thinking.

A 1941 landscape report on the Bartow-Pell site concluded that the tree that perished in 1906 was not the tree beneath which Thomas Pell signed his fateful Treaty with the Siwanoys. The report said:

Just as the Bartow Mansion had been erroneously thought to be the Pell Manor House, over time the oak that was enclosed in the iron fence became associated with the Treaty Oak. However, numerous accounts by long-time local residents seem to have put the matter to rest. . . . With the erection of the iron fence in 1903, the site of this oak tree seemed to be indubitably linked with the historic event of 1654. However, the claim was refuted in an article in the Seventeenth Annual Report of the American Scenic and Historic Preservation Society (1912) which stated that the iron fence in the Bartow House grounds does not indicate the site of the Treaty Oak. In addition to studying the written sources, the author had consulted with Anne J. Bolton, the daughter of the Rev. Robert Bolton who lived nearby in Pelham, who said that it had stood between the Pelham Bridge and the entrance to the Bartow place alongside the Post Road; she remembered that, travelers on the Post Road were accustomed to stop their horses under its branches to enjoy its refreshing shade. Later authors writing about Pelham Manor noted the disputed claim, but acknowledged, that despite a possible historical inaccuracy, the iron fence helped to keep alive the memory of the treaty between Thomas Pell and the native Americans.

We will never know whether the oak that perished in 1906 was, in fact, the tree beneath which the famous Treaty was signed. Somehow that does not seem important. Thomas Pell’s Treaty Oak came to symbolize the sacrifice – and glory – of those before us who carved Pelham and much of today’s Westchester County out of the primeval forest that still existed in the 17th century, beginning on that day in 1654…

Bartow-Pell Mansion Museum

The plot is surrounded by low iron railings connecting four corner granite posts engraved with the Pell family coat of arms, the pelican. It was erected in 1891 by descendants of Benjamin Pell, grandson of Thomas Pell, Lord of the Manor according to the inscription on one of the posts.

The largest marker is a memorial to the Pells erected in 1862 by James K. Pell and is inscribed with these words:

“This stone is placed here in token of respect for the memory of and to mark the place where lie buried the mortal remains of several of the descendants of John Pell, who was born in the year 1643 and died in the year 1700, the son of the Rev. John Pell, D.D. of Essex, in England, and the nephew of Thomas Pell, the first proprietor of the Lordship and Manor of Pelham, born in the year 1603 and died in the year 1669.”

The north post reads: “Indian grant of Pelham Manor to Thomas Pell, Nov. 14, 1654”

The west post reads: “Royal Patent Oct. 6, 1666, Duke of York to Thomas Pell, First Lord of the Manor”

The south post reads: “Royal Patent, Oct. 25, 1687, James II, to John Pell, Second Lord of the Manor, First Judge, 1688, and First Member of the Provincial Assembly, 1691, of Westchester County.”

The east post reads: “Pelham Bay Park, 1884. Erected 1891 by descendants of Benjamin Pell, grandson of Thomas Pell, Lord of the Manor.”

The Pell and Robert Bartow Family Relationships

Joseph Pell (1722-1752). Joseph was the oldest brother of Robert Bartow’s great-grandmother Bathsheba Pell Bartow.

Sussannah Pell Drake (1741-1763). Sussannah was a daughter of Joseph and Phoebe Pell. Her brother, Thomas Pell, married Margaret Bartow, Robert Bartow’s great-aunt. In 1790, 200 acres of the Pell estate property were conveyed to John Bartow, Robert Bartow’s grandfather, by his brother-in-law Thomas Pell.

Four headstones within the plot date between 1748 and 1790 mark the graves of Pell family members who were buried on the property when the site was occupied by the Pell manor house. In chronological order according to date of death, the inscriptions of Isek Pell, Joseph Pell, Sussannah Drake, and Phoebe Pell read:

Isec Pell headstone Isec Pell

“Her lyes Isec Pell, D. Dec. 14, anno 1748”

Joseph Pell headstone Joseph Pell

“Is her the body of Joseph Pell, eged 31, D. 1752”
Joseph Pell, 4th Lord of the Manor, was the son of Anna and Thomas Pell II and was married to Phoebe Pell.

Sussannah Pell Drake headstone Sussannah Pell Drake

“In Memory of Sussannah, wife of Benjn. Drake, who died March 4th 1763; Aged 22 years.”
Sussannah was a daughter of Joseph and Phoebe Pell. She married Benjamin Drake on December 29, 1759. After her death he married three more times.

Phoebe Pell headstone Phoebe Pell

“In Memory of Phoebe Pell, the widow of Joseph Pell. She departed this life on the 22d day of March, 1790, in the 70th year of her age.”
Phoebe Pell was married to Joseph Pell, who died in 1752. On November 18, 1762, she married James Bennett.

The following two stones are currently stored inside the Bartow-Pell Mansion Museum. The inscriptions on these stones read:

Here lyes the body of Saloma Pell, born Jan. ye 13th, 1759, and departed this life Octr. ye 10th, 1760. Aged 1 year, 8 months & 27 days.

In Memory of John, son of James and Phoebe Bennett, who died Augt. 6, 1765, aged 2 months.

John Bennett was a son of James and Phoebe Pell Bennett (Joseph Pell’s widow).
