Ramsay was the son of A. W. Ramsay of Ayr. He was educated at Edinburgh University where he read law, obtaining MA and LL.B degrees. He does not seem to have ever married.
According to reports Ramsay was always a keen proponent of his native country, its institutions and traditions. He was sometime President and Chief of the Scottish Clans Association of London; a trustee and Elder and Session Clerk of St Columba's Church, in Pont Street, Knightsbridge and was Treasurer and Convener of the Maintenance of the Ministry Fund of the Church of Scotland in England. He was also a life member of many Scottish Societies.
Politics
Ramsay's first attempt to enter Parliament came at the 1922 general election when he stood as a Lloyd GeorgeNational Liberal candidate in the Glasgow Shettleston constituency. Ramsay did not stand for election at the general elections of 1923 or 1924 but was adopted as candidate for the Liberal seat of Western Isles at the 1929 general election when the sitting MP Alexander Livingstone announced he was standing down. At the election Ramsay faced a three-cornered contest against Labour's John Macdiarmid, a retired railway auditor and Unionist candidate Captain Ian Moffat-Pender, a former Scottish Rugby international. Ramsay held the seat for the Liberals with a majority of 1,288 votes over Labour, with the Tories in third place. Ramsay seems to have been an assiduous member of the House of Commons. It was reported in The Times newspaper that he put in the most attendances at divisions for the Liberal Party in 1930 with 441 attendances out of a possible 484.
National Liberal
In 1931 an economic crisis led to the formation of a National Government led by Labour prime ministerRamsay MacDonald and initially supported by the Conservative and Liberal parties. However the Liberals were increasingly divided over the issue of the National Government, particularly over the issue Free Trade. The official party led by Sir Herbert Samuel became more and more worried about the government's stance on Free Trade and worried about the predominance of the Conservatives in the coalition. However a group of Liberal MPs led by Sir John Simon who were concerned to ensure the National Government had a wide cross-party base formed the Liberal National Party to more openly support MacDonald's administration. Ramsay became one of the founder members of this group and thereafter sat in the House of Commons as a Liberal National. He held his seat at the 1931 general election in a straight fight with Moffat-Pender for the Conservatives. At the 1935 general election, Ramsay was not opposed by an official Liberal candidate or his Unionist coalition partners, but he was faced by Labour's Malcolm Macmillan and an Independent candidate representing the Scottish National Party, Sir Alexander MacEwen. Macmillan won the seat with a majority of 1,345 votes and at 22 years of age became the youngest member of the House of Commons. Ramsay was one of the possible National candidates for the by-election which occurred in Ross and Cromarty when Sir Ian Macpherson announced he was to stand down on medical advice. In the event the constituency chose Malcolm MacDonald the son of the Prime Minister to contest the by-election. Ramsay did not stand for election again.
Death
Ramsay died in London on 20 October 1956, aged 79 years. A memorial service was held for him at St. Columba's Church in Pont Street on 13 November 1956 at which his sister was the chief mourner and which was officiated by the Moderator of the Church of Scotland the Right Reverend Dr R F V Scott.
