Four of his sons, the third, fourth, fifth and sixth Viscounts, all succeeded in the peerages. The sixth  Viscount was succeeded by his first cousin once removed, the seventh Viscount.

He was the son of James Waller O'Grady, younger son of the Honourable Waller O'Grady. Lord Guillamore died unmarried and was succeeded by his younger brother, the ninth Viscount. The titles went unclaimed on his death in 1955. Several other members of the O'Grady family have gained distinction. Hayes O'Grady (died 1864), brother of the first Viscount, was an  Admiral in the Royal Navy. His son was the antiquarian Standish Hayes O'Grady. The author, journalist and historian Standish James O'Grady was the grandson of John O'Grady, brother of the first Viscount.
