Fourth child of Peter and Caroline O’Reilly, Jack was born at Point Ellice House and was educated in England from the age of nine.

Jack was fond of tennis, golf, and especially croquet. He also enjoyed fishing and hunting. In 1914, Jack married Mary Windham in England. During the First World War, he served in the Royal Navy and later became a major in the Royal Naval Air Service. Like his brother, Jack was an active member of the Conservative Party. Jack lived at Point Ellice House with his wife Mary until his death in 1946, the last of Peter and Caroline O’Reilly’s four children.
