Banker. Born Edinburgh. With his brother, James, came to London and worked in a bank founded in 1692 by John Campbell. James married Campbell's grand-daughter and through her inherited the bank. Thomas and James ran the, renamed, bank and on James's death in 1778 Thomas took sole charge. For his love-life see Baroness Burdett-Coutts, who was his granddaughter by Sophia, one of his three daughters.
He preferred his less grand house, Holly Lodge, West Hill, Highgate, to his town mansion at 1 Stratton Street, on the corner of Piccadilly. Some sources say he died at Holly Lodge but we are informed by our contact at the bank that it was Stratton Street.
