At the 1852 general election, North was returned to Parliament as one of three Members for Oxfordshire,[2] a seat he held until the constituency was divided at the 1885 general election.
[citation needed] He was also a Colonel in the British Army.
In 1841 the barony of North held by Lord Guildford was called out of abeyance in favour of Lady Susan, who became the tenth Baroness North.
She died in March 1884, aged 87, and was succeeded by her and North's son, William.
North survived his wife by ten years and died in October 1894, aged 90.
