Windsor was the second son of
Thomas Hickman-Windsor, 1st Earl of Plymouth, by his second wife Ursula Widdrington, daughter and co-heiress of
Sir Thomas Widdrington,
Lord Chief Baron of the Exchequer, and Frances Fairfax. He was made a
Page of Honour to
James II in 1685 (a post he held until the king was deposed in 1688) and a few months later was returned to Parliament for
Droitwich, despite being only around sixteen at the time.
Lord Willoughby de Eresby wanted both him and
Peter Legh (died 1744) expelled as minors. Windsor took no part in the proceedings of Parliament and was not re-elected in 1687. This being an Irish peerage he was still eligible for election to the English House of Commons, and in 1705 he was once again returned to Parliament for
Bramber, a seat he held until 1708. Between 1708 and 1712 he represented
Monmouthshire. The latter year he was created an English peer as
Baron Mountjoy, in the
Isle of Wight, as one of twelve peers created to secure a
Tory majority in the
House of Lords. They had six children: two sons and at least four daughters: • Hon.Thomas Philip (baptised 6.2.1706 St.Luke's, Chelsea) •
Herbert Windsor, 2nd Viscount Windsor (1707–1758) ⚭ 1735 Alice Clavering • Hon. Ursula Windsor ⚭ 1736 John Wadman • Hon. Charlotte Windsor ⚭ 1736 John Kent • Hon. Catharine Windsor (1716–1742) ⚭
Mattheus Lestevenon (1715–1797), • a daughter who died at a young age Charlotte died in November 1733. Lord Windsor died in June 1738 and was succeeded in his titles by his son,
Herbert. He inherited the Lower Avon Navigation from his father, who had acquired the rights to it from the future King
James II of England. ==References==
