Staples was a barrister in Dublin and was appointed a Queen's Advocate in Ireland in 1845.

He lived at Lissan House. Staples married Catherine Hawkins, daughter and heiress of Reverend John Hawkins and Anne Montgomery, on 27 October 1813; they had no children and his title was inherited by his nephew.
