Montagu Bertie, 5th Earl of Abingdon, graduated from Oxford University with a degree of Doctor of Civil Laws. He held the office of High Steward of Abingdon in 1826 and Lord-Lieutenant of Berkshire. He also served as a cup-bearer at the Coronation of King George IV.
Bertie's first wife, Emily Gage, was the daughter of General Hon. Thomas Gage. General Gage served as colonial governor of Massachusetts, and his agressive actions against the colonists contributed to the American Revolution. In April 1775 Gage ordered British troops to Lexington and Concord, and after the Battle of Bunker Hill he was recalled to England.
