John Gordon Jameson

Major John Gordon Jameson (1878–1955) was Unionist Party MP for Edinburgh West.
He was also an advocate, and his father was Andrew Jameson, Lord Ardwall.
He unsuccessfully contested the Edinburgh East by-election, 1912, where he had already been selected as the Unionist candidate before the MP died. (At that stage he was nominally a Liberal Unionist, although they merged with the Conservatives only three months later.)
He was elected in Edinburgh West as a supporter of David Lloyd George's coalition government in 1918, but he lost his seat to the Liberals in 1922.
