Christopher, as well as being a judge, was a noted religious polemicist. Both brothers were friends of James Ussher, appointed Archbishop of Armagh in 1625, who encouraged Christopher to write more.[2] This friendship no doubt fostered the career of Robert, who presumably shared his brother's Puritan and Anti-Catholic beliefs, (as did Ussher). Thomas Wentworth, 1st Earl of Strafford, Lord Lieutenant of Ireland, also praised Robert as an "honest and able man", and he has the respect of his fellow Bishops, who in 1640 recommended him for the vacant See of Ossory.
Neither he nor Christopher had any children, and their property passed to the children of their brother William Sibthorpe of Dunany, of whom we know most of their niece, Lucy. Lucy married Henry Bellingham of Gernonstown, County Louth, ancestor of the Bellingham Baronets of Castlebellingham.[5] John Sibthorpe, a barrister of the King's Inns in the 1620s, was no doubt another family member.[6]
