There are many discussions of Hugh FitzBaldric and his extensive landholdings in Conquest, Anarchy and Lordship: Yorkshire, 1066-1154 By Paul Dalton (available online through Googlebooks).

When the land of the Saxon earls was confiscated [by the Normans] after the Conquest it would appear that Orm’s property was acquired by, or granted to, Ralph de Mortimer; and Barch’s by Hugh FitzBaldric.

... let us follow what is known about Barch’s portion. As we have already seen, it was granted to Hugh FitzBaldric (i.e. Hugh the son of Baldric). It is not known which Norman family he came from, if indeed he was Norman. It has been stated that he was a German archer in the service of William the Conqueror. However, before 1067 he “witnessed a charter of Gerald, granting the Nuns of St. Amand in Rouen the church of his fief of Roumare”. Immediately after the capture of York by William in September 1069, Hugh FitzBaldric appears to have been made Sheriff of the County of York by the King. He fell into trouble by supporting Robert Duke of Normandy against William and presumably lost his lands. However, nothing more is heard of him.

... In 1284/5 ... the land of Hugh Fitzbaldric, assessed at 2½ carucates, became part of the fee of [Roger de] Mowbray.
