We do not know the NAME of the wife of Ranulf de la Haye. We do know that she was the "daughter of Thurstan Haldup and his wife (name also unknown).

From Cawley Medieval Lands Database:

RANULF . Seneschal of Robert de Mortain. m ---, daughter of THURSTAN Haldup & his wife ---. Her parentage and marriage are confirmed by the foundation charter of the priory in which her son Robert de La Haye names himself "son of Ranulf the seneschal of Robert de Mortain" and "nephew of Eudo dapifer" [son of Thurstan Haldup][1595]. Ranulf & his wife had one child:

i) ROBERT de La Haye ([1075/80]-[1150]). A manuscript recording the founding of Boxgrove Priory, Sussex states that it was founded by “Roberti di Haya…consanguineo eius” [referring to King Henry], to whom Henry I King of England had granted “honorem Halnaci” [Halmaker] in Sussex, and given to the abbey of Essay in Normandy[1596]. According to Domesday Descendants, this was land which had been forfeited by William de Ansleville[1597]. In the foundation charter of the priory he names himself "son of Ranulf the seneschal of Robert de Mortain" and "nephew of Eudo dapifer" [son of Thurstan Haldup][1598]. Domesday Descendants dates the foundation to "before 1105"[1599], which would place Robert´s birth in [1075/80], bearing in mind his date of death. Henry II King of England confirmed the possessions of the abbey of Lessai, including donations by "Turstini Haldup et Eudonis filii eius" confirmed by "Roberti de Haia et Murielis uxoris sue et Richardi et Radulfi filiorum eorum", by charter dated [1185/Jan 1188][1600].
