He was the son of William Hanmer (born ca. 1648,
Angers, France, died ca. 1678?, the son of
Sir Thomas Hanmer, 2nd Baronet), and of Peregrine, daughter and co-heiress of
Sir Henry North, 1st Baronet, of
Mildenhall,
Suffolk. He was born between 10 and 11 p.m. in the house of his grandfather
Sir Thomas Hanmer, 2nd Baronet, at
Bettisfield Park, near
Wrexham,
Clwyd, Wales (formerly
Flintshire). His father, William, seems to have died early, and Thomas was educated in
Bury St Edmunds, at
Westminster School and
Christ Church, Oxford, matriculating on 17 October 1693, age 17. His tutor was
Robert Freind,
D.D., who was later under-master at Westminster in 1699, and headmaster 1711–1733. Hanmer gained his
LL.D., however,
Com. Reg. from
Cambridge University in 1705. He succeeded as 4th Baronet in 1701, when his uncle, the 3rd Baronet
Sir John Hanmer, died in a duel He was a
high church Tory M.P. for
Thetford in 1701–02 and 1705–08; for
Flintshire in 1702–05; and for
Suffolk in 1708–27. He was unanimously elected
Speaker of the House of Commons in February 1714, during the last Tory government for over 100 years; the Tory party was split between those (like Hanmer) who wished to maintain the Protestant succession in Britain, and those with
Jacobite tendencies who supported
James Stuart, the 'Old Pretender' of the
Jacobite succession. After the death of
Queen Anne in August 1714,
George I brought in a government composed entirely of
Whigs. The House of Commons was dissolved in January 1715, and Hanmer was not put forward for re-election: in his stead
Spencer Compton (later 1st Earl of Wilmington and
Prime Minister) was elected Speaker on 17 March 1715, although Hannmer continued to serve as an MP until 1727. The Tory party was proscribed from government office until 1760 and the accession of
George III. He was one of the founding governors of the
Foundling Hospital, a charity set up for London's abandoned children in 1739, which also became a centre for the arts. He also built and endowed a home for the impoverished elderly in Mildenhall, his mother's home village, in 1722. The home, called Bunbury Rooms for his brother-in-law and biographer Henry Edward Bunbury, serves a similar purpose today. ==Literary activities==
