General Gervais Parker (also spelt Gervase; 1695 – 19 June 1750) was a British Army officer.
For the final decade of his life, he served as Commander-in-Chief of the Royal Irish Army during the reign of George II.
He was the elder surviving son of the Jacobite Colonel John Parker by his first wife Johanna Rouse.
The family went into exile in France following Colonel Parker's service at the Battle of the Boyne, but Gervais escaped from his father and joined the English army.
[1] Parker was commissioned an ensign in the 1st Regiment of Foot Guards on 27 December 1690,[2] and his early career was assisted by his Williamite relatives.
