J.P., F.S.A. of Lincoln’s Inn. Admitted an attorney of King’s Bench June 28th, 1773, and a Fellow of the Society of Antiquities, 29th April, 1808. He succeeded to the family estate at Edmond Castle, but only survived his father a few years. He died June 23rd, at Clapham Commons, and was buried in the vault belonging to his wife’s family at Acton, Middlesex.

Became a partner in James Coulthard’s law firm.

Note that his children had extensive connections with Clapham Commons and Eastbourne. Clearly this is where the family was based, not at Edmond Castle. He was clearly the heir of Edmond Castle, but for one reason or another chose to live elsewhere, possibly to further his law practice.

From the Lambeth Archives Department:
“The Graham family of Edmond Castle, Cumberland, became linked with Clapham through the marriage, in 1791, of Thomas Graham with Elizabeth Susannah Davenport. Her father, John, a wealthy merchant (he was Master of the Merchant Taylors' Company in 1775) and woollen draper to the King had bought a large estate on Clapham Common Northside, near the present Sugden Road. Thomas and Elizabeth had five children, Thomas Henry, John, Elizabeth Maria, (known as Maria), Emily and Ann Margaret. After Thomas' death in 1813 his eldest son inherited Edmond Castle but the children continued to live with their widowed mother at The Hall for some years. John moved to Rose Lodge (later Northfield) Clapham in 1833, and returned to The Hall on his mother's death in 1844. He left in 1853, and in 1886 the estate was sold for development Of his three sisters, Maria remained unmarried, and was instrumental in the building of St George's Church, Battersea with its associated school and vicarage. Emily married the Rev Thomas Collins, and Anne married Edward Polhill. The Polhill family had a large house on the site of Crescent Grove.”

Of Clapham Common, Surrey.
A church plaque in Hayton [14] reads:
“Elizabeth Susanna, relict [sic. Relict!? What the hell is that?] of Thomas Graham Esq died at her house at Clapham Common, Surrey, Aug 10 1844 in her 82nd year, and was buried in the vault of the Davenport family at Acton.....This tablet was erected to the memory of his revered and beloved mother, as a tribute of his warm and tender affection, by her son Thomas Henry Graham.”

“ESD was the author of 1) "Eighteen Maxims on Neatness and Good Order", Hatchard under the pseudonym Theresa Tidy.  2) Writing as Lemuel Gulliver Jr. "Voyage to Locuta" Hatchard 1818. 3) The Snow-Drop. 1830. I [PB] have a manuscript diary of hers completed between 1780-83
She lived at The Hall on Clapham Common, Northside until her death.” [28]

This coat-of-arms on the bookplate is very interesting indeed, showing as it does the Graham escallops on the diagonal. This is just like the coat-of-arms of Thomas Graham’s son (Thomas Graham), as carved on an outside wall of Edmond Castle, and joined with the Carnegie coat of arms. Maybe the Grahams of Edmond Castle, contrary to everything else I’ve been told, or seen, did actually use the escallops in bend, not in chief. Strange, indeed.
