Patrick Riddick was one of the sons of John and Elizabeth and he was born in 1885. He married Catherine Murphy on 24 September 1919 in St Andrew's, Dublin. Catherine was a sister of my great grandfather Daniel and was from Rathdrum in Co. Wicklow. Patrick passed away on 15 September 1947 and is buried with his wife in St. Fintans, Deansgrange Dublin.
