Wigram, whose parents were patrons of unitarianism, was baptized at the instigation of his paternal grandmother. He became a partner in his father’s mercantile concern at 3 Crosby Square, Bishopsgate by 1794 and, with his father and brother John, signed the London merchants’ declaration in favour of Pitt in 1795, but Farington reported in 1809 that ‘he retired from business at his father’s desire from whom he expects a large addition of property’, with £30,000 ‘independent of him’. The fact was that Wigram lacked his father’s business acumen, though he was a Bank director for many years.
In January 1806 Wigram asked the assistance of Pitt’s secretary in obtaining a seat in Parliament ‘in the present session’, believing his politics to be ‘well known’ to Dacres Adams. He mentioned Boroughbridge, if ‘not engaged’, and Leominster, but added that his father wished to avoid a contest. Adams could not then help him and Wigram wrote again that his father was ‘very sanguine of my success at the Bank in April, which adds to my wish to take my seat in the House at the opening of the session, when I shall have leisure for a constant attendance’.
He gave a general support to successive administrations, though he apparently refused a seat on the Admiralty board in the Portland administration (1807), because of his handicap of occasional deafness.
Wigram subsequently developed feudal tendencies. He was ‘one of the last of the heirs of baronets who claimed a knighthood in his father’s lifetime’, conferred on him by the Prince Regent at Carlton House in 1818. Later he changed his name to Fitzwygram, ‘a fanciful alteration’, which was not adopted by other members of his family. He died 17 Dec. 1843. The Prince Regent and Duke of Clarence, and the Dukes of York and Wellington stood sponsors to his second and third sons. His character was ‘strictly English’.
