Rushout Cullen

Cullen was the son of Sir Abraham Cullen, 1st Baronet, MP of East Sheen, Surrey and Upton near Banbury in Warwickshire, and his wife Abigail Rushout, daughter of John Rushout, merchant of St Dionis Backchurch, London and Maylords, Havering, Essex.

At the 1695 English general election he stood on the suggestion of his brother-in-law, Sir James Rushout, 1st Baronet at Evesham, but, being an outsider, was narrowly defeated.

At the 1705 English general election he topped the poll in a close contest and voted for the Court candidate for Speaker on 25 October 1705.

At the 1708 British general election, he was returned unopposed and continued to support the Whig administration acting as teller twice in the first session.

He had one daughter, Mary, who married Sir John Dutton, 2nd Baronet but no male heir, so the baronetcy became extinct.
