David de Offington

Sir David de Offington (died c.1312) was an English-born Crown official in late thirteenth-century Ireland. He was one of the earliest recorded holders of the office of High Sheriff of County Dublin and the first recorded Baron of the Court of Exchequer (Ireland). He became a substantial landowner in Leinster. He first appears in Ireland as custodian of the Irish estates of George de Cantilupe, Lord of Abergavenny, who attained his majority that year, but died a few months later. David was Sheriff of County Dublin (one of the earliest named Sheriffs: Ralph Eure, who was probably the first, was appointed in 1258), and Constable of Newcastle, County Wicklow in 1282, and other lands in County Carlow. He seems to have lived mainly at Ballykenna, as evidenced by his last will.

He was appointed Baron of the Irish Exchequer in 1294: His son Thomas succeeded to his estates.
