By 1703 he had become deputy to Garter King-at-arms , and it appears from a letter sent to him ( 1710-11 ) by William Lewes that he had the sole right of registering Welsh genealogies apart from those relating to the counties of Cardigan and Radnor . He had intended to publish the Historic of Great Britain … ’til the Death of Cadwaladr , written by John Lewis of Llynwene , with some additions of his own, but this did not appear until 1729 (see Francis Payne 's article in Y Llenor , Oct. 1935 ). The Golden Grove Book of Pedigrees , now in the P.R.O. , is based on the work of Hugh Thomas and William Lewes .
Hugh Thomas lived in Bloomsbury. He d. 22 Sept. 1720 , and was buried in S. Martin-in-the-fields ; his will is dated 14 Sept. 1720 ( Edward Owen , op. cit., ii, 491) and was proved 6 Oct. ( Trans. Carm. Antiq. Soc ., xv, 60). (The dates 1715 and 1721 given in various editions of Theophilus Jones and in other books are, of course, incorrect.) As he had no children, his widow Margaret , daughter of George Wood of Abergavenny , was the sole beneficiary under the will, apart from certain legacies. His collection of pedigrees and other manuscripts was left to Robert Harley , earl of Oxford , and so, ultimately, came to the British Museum . He had a brother who, according to the will, was heavily in his debt and had been a burden to him all his life; yet he left him ten pounds. But, according to Theophilus Jones , Harley gave this brother a substantial sum of money, ‘as he was very poor,’ by way of thank-offering for the manuscripts. Two of Hugh Thomas 's kinswomen (one of whom, at least, was probably his sister) lived at Brecon .
