Sir John Guise, 3rd Baronet (c. 1677–1732) of Elmore Court, Gloucestershire was a British landowner and politician who sat in the House of Commons between 1705 and 1727.
[1] He was granted the office of Constable of Gloucester Castle in May 1690, at the age of 12 and his father put him forward at the1695 general election for Cirencester.
His father's estate was in a parlous financial state, and he was bound by his wife's trustees in a tight marriage settlement which forced him to retrench.
She was Anne, the daughter of Sir Francis Russell, 3rd Baronet MP of Strensham, Worcestershire whom he married by licence dated 2 January 1711.
[2] In 1719 Guise bought the manors of Harleyford and Great Marlow from Sir James Etheridge, MP thus acquiring a strong political interest there.
