He was the son of Moses Aaron Senior and Elizabeth Baldrick Halsey, the husband of Frances Raven, the father of John Raven Senior [and hence the grandfather of the economist Nassau William Senior] and Elizabeth Baldrick Senior, the brother of Ascanius William Senior, and the half-brother of Robert Halsey Baldrick and Charles Adam Baldrick. Owner of Baldrick’s, St John, Barbados and Pool’s plantation in St Joseph and St Andrew. He also held a mortgage on the Harrow plantation, 1777-1790.
