History of Anna Maria Graham Family Unit
From the 'Book of the Graemes and Grahams' by Louisa Grace Graeme, we have the following:

Thomas Graham the fourth and youngest son of John Graham of Kernock (Helen's third son) was born on the 5th October 1752, he also went to India and was member of the Supreme Council of Bengal; he married Ann Paul, a daughter of Henry Paul, Esq.; Mr Strangeways writes of her and her sister (who became the wife of George Templer Esq., of Shapwick, Devon, which estate he purchased from the Rolls on his re-turn from India) they were the most beautiful women ever married in India.

Thomas, on his return from India with his wife Ann Paul, bought the Manor of Burleigh and also succeeded to the estate of Kinross from his half-brother George Graham (as mentioned on pages 597-8). An only son and two daughters were born of the marriage, the son born in 1784 was brought up by his aunt, Mrs Templer of Shapwick, he unfortunately lost his life in 1808 when on his way to India at the taking of the 'Kent'.

Thomas Graham, who had by that date inherited Kinross, left that estate to whichever of his two daughters should first have a son; both married; the eldest, Ann, became the wife of her cousin the Rev. G. H. Templer, Rector of Shapwick (son of George Templer and the lovely Miss Paul), their daughter was named Sophia and married H. Strangeways, Esq., and has issue. The younger daughter of Mr Graham of Kinross and Ann Paul was Helen, she married Sir James Montgomerie of Stobo Castle, Baronet and M.P. for Perthshire, and becoming the mother of a son brought the estate of Kinross to the Montgomeries of Stobo Castle, who thus represent the Grahams of Kinross.
