What is the documentation for the mother attached here on Geni?
The Wikipedia pages for Eustace and his father John don't mention his mother and Medlands says she is unknown:

JOHN, son of [RICHARD & his wife ---] . A document records that the abbot of Mont Saint-Michel had wrongfully sold property to “Ranulf the moneyer” but that it was inherited by “Gualeran son of Ranulf” who sold it back to the abbey, that it was claimed by “John of Richard” who “some fifteen years…later” seized the property, judgment in the ensuing dispute being awarded to the abbey[389]. A manuscript concerning the founders of Watton priory records that “Johannis pater primi Eustachii et Serlo de Burgo, sive de Pembrok” were brothers[390]. The Complete Peerage sets out the arguments which refute this hypothesis[391].
m ---. The name of John’s wife is not known.
