David de Offington

David de Offington (died 1299) was an English-born Crown official in late thirteenth-century Ireland. He was apparently of the first recorded holder of two offices, High Sheriff of County Dublin and Baron of the Court of Exchequer (Ireland).

He came to Ireland about 1273. Seven years later he received a royal pardon for all trespasses committed in England, and made repeated journeys back to his home country. He first appears in Ireland as custodian of the Irish estates of George de Cantilupe, who attained his majority that year but died a few months later. David was Sheriff of County Dublin and Constable of Newcastle, County Wicklow in 1282. He was also seneschal of Kilkenny and custodian for the Irish lands of Gilbert de Clare, 7th Earl of Gloucester. He travelled to Connacht on unspecified "KIng's business".

He was appointed Baron of the Irish Exchequer in 1294: the Court was a very recent creation, and this was some years before the first Chief Baron of the Irish Exchequer was appointed. David seems to have been the first Baron, and was joined by Richard de Soham the following year. He died in 1299.
