Patrick Bowes-Lyon was born on 22 September 1884 at
St Paul's Walden Bury, Hertfordshire to
Claude, Lord Glamis, and
Cecilia Cavendish-Bentinck. Styled as
Master of Glamis from birth, he became
Lord Glamis when his father inherited the earldom in 1904. Strathmore and three of his three surviving brothers all served in
World War I. He was a major in 1/5th Battalion, the
Black Watch. His brothers
John and
Fergus also served with the Black Watch, the latter being killed in action at the
Battle of Loos, while his younger brother
Michael served with the
Royal Scots and was taken as a prisoner of war. On 19 June 1920, he was appointed a
deputy lieutenant of
Forfarshire (Angus from 1928). He succeeded his father as 15th and 2nd Earl of Strathmore and Kinghorne (15th earl in the
peerage of Scotland and 2nd earl in the
peerage of the United Kingdom) on 7 November 1944. He was the eldest brother of
Lady Elizabeth Bowes-Lyon (later Queen Elizabeth the Queen Mother), and thus an uncle of
Queen Elizabeth II and
Princess Margaret. As an uncle of the bride, Strathmore was a leading guest at the 1947
wedding of Princess Elizabeth and Philip Mountbatten. ==Marriage and issue==
