Robert St Lawrence, 3rd Baron Howth

Robert St Lawrence, 3rd Baron Howth (born c.1435 – died before 1488) was a leading statesman in 15th-century Ireland who held the office of Lord Chancellor of Ireland, and was through marriage a close connection of the Tudor dynasty.

He was born about 1435, eldest son of Christopher St Lawrence, 2nd Baron Howth. There is some dispute about the identity of his mother: some sources name her as Anne Plunkett, others as Elizabeth Bermingham. He succeeded to the title in 1464 or 1465.

O'Flanagan calls him "a nobleman of considerable abilities, who filled several offices connected with the Government of Ireland."

He was High Sheriff of County Dublin in 1456, Chancellor of the Exchequer of Ireland in 1478 and Clerk of the Court of Common Pleas (Ireland). In 1474 he was chosen to be one of the thirteen Knights of the Brotherhood of Saint George, who were charged with defending the Pale against invasion by neighbouring Gaelic clans, and more generally with keeping the peace.

In 1483 Richard III chose him to be Lord Chancellor of Ireland, despite opposition from Gerald FitzGerald, 8th Earl of Kildare, who was then almost all-powerful in Ireland. His continued employment by the Yorkist kings after his second marriage in 1478 is perhaps surprising, given that his second wife Joan Beaufort was a close relative of Henry Tudor, who was to overthrow the House of York in 1485. In any event his tenure as Lord Chancellor was short, ending either with his removal or his death later in 1483, although some sources place his death as late as 1487.
