[1] He was the son of Sir James Graham, 1st Baronet and his wife Anne Moore, daughter of the Rev.
Graham replaced John McMahon there, and held the seat for half a year to the 1812 general election.
[3] He was not a candidate in that election: while his father considered that his support for the new Liverpool administration should have meant a seat being found for Graham, Charles Long excused the Tory omission since there were other demands.
[1][4] During 1813 Graham voted consistently for Catholic relief, against his father's wishes; and in 1815 he was deprived of the Ludgershall seat, with Charles Nicholas Pallmer taking the place.
At the 1818 general election his father relented, and Graham was back in Parliament for Ludgershall, now de facto a Whig supporter on most issues.
