Also known as Robert FitzRoy. Orderic Vitalis records him as "Robert the king's son", and specifies that he led a force from the Cotentin in Sep 1123 to quell the rebellion led by Amaury de Montfort Comte d'Evreux and Waleran de Beaumont Comte de Meulan. According to the Gwentian Chronicle, Robert was the king’s son by "Nest, daughter of Rhys son of Tewdwr, who was afterwards the wife of Gerald of Pembroke Castle", but this appears unlikely from a chronological point of view.
He was created Earl of Gloucester in [Jun/Sep] 1122. He had the custody of his uncle Robert ex-Duke of Normandy as a prisoner at Bristol in 1126. He did homage to King Stephen in 1136, but quarrelled with him in 1137, and his English and Welsh estates were forfeited. He joined forces with his half-sister "Empress" Matilda, landing in England with her in Sep 1139. He became her commander-in-chief in the civil war. After a series of successes against King Stephen’s forces, including the capture of the King at Lincoln in Feb 1141, he himself was captured at Stockbridge 14 Sep 1141 and imprisoned at Rochester. He was freed shortly after in exchange for the king.
The Gesta Stephani Regis records the death of "comes…Glaorniæ" at Bristol, dated from the context to . 1
Robert married Mabel (Matilda or Sibyl) FITZ HAMON, daughter of Robert FITZ HAMON, Earl of Gloucester, Lord of Glamorgan and Sibyl DE MONTGOMMERY, before 1112 in Gloucestershire, England. (Mabel (Matilda or Sibyl) FITZ HAMON died about 29 Sep 1157 in Bristol, Gloucestershire, England.)
