Robert Sibthorp

Robert Sibthorp(e) was an Anglican bishop in Ireland during the first half of the seventeenth century.

He was born at Great Bardfield, Essex, one of the three sons of John Sibthorpe. His mother may have been called Jane Berners, but this is uncertain. Sir Christopher Sibthorpe (died 1632), justice of the Court of King's Bench (Ireland), was one of his brothers. In 1643 he was translated to Limerick, where he found that the Diocese had been so utterly wasted by the ravages of the Civil War that he was unable to derive any revenue from his bishopric. He died in April 1649 and was buried in St. Werburgh's Church, Dublin.

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. John Sibthorpe, a barrister of the King's Inns in the 1620s, was no doubt another family member.
