Nothing of his background is known except his kinship to the English and Norman leadership and that his byname appears to be a Breton name, Wiomar'ch. He was brought to England by Edward and had a successful career, being rewarded with numerous lands in various parts of the country. He had a special interest in Essex and set up his main base at Clavering. It was to Clavering that many of Edward's Norman favourites fled when they were ousted from political power in 1052, before taking ship into exile. Despite being a Norman, Robert stayed in England and found further favour with Edward, and possibly with Harold Godwinson after him.
Robert was later made Sheriff of Essex and was described as regalia palatil stabilitor - high officer or sometimes staller - of the royal palace. When Edward died in January 1066, Robert was one of the four inner councillors present at his death bed, along with the Queen, Edith of Wessex, Earl Harold Godwinson and Archbishop Stigand, an event captured on the Bayeux Tapestry.
Robert seems to have acquiesced with Harold's succession to the throne, but also seems to have kept in touch with his homeland. When William landed at Pevensey it was Robert who contacted him to advise a retreat back to France. The advice was, apparently, that William had neither the strength nor numbers to win a battle against Harold, particularly as Harold was buoyed by his victory against the Norwegians at Stamford Bridge.
Robert clearly remained in favour with William after his victory at Hastings, and subsequent succession, as he retained his estates, and was further rewarded with others. He left his extensive estates to his son Suen (Swein of Essex), who went on to build Rayleigh Castle.
He is remembered in Rayleigh, Essex, where one of the town's secondary schools is named The fitz Wimarc School.
