Further confirmation on the identity of Eleanor, wife of Ralph FitzBernard comes from VCH Surrey v.3 p.48 under the section on the manor of Peper Harow
"The actual tenant of Peper Harow in 1086 was a certain Girard one of whose successors, Osbert of Peper Harow, sold Peper Harow to Ralph de Broc. His son-in-law Stephen de Turnham received a confirmation of the sale from King John in 1205. Stephen's daughter Clemency received Peper Harow as her portion on her marriage with her first husband Alan de Plugenhay; she afterwards married Wandrith de Corcell, and her third husband, Henry Braybrok, who evidently survived her, sued Ralph son of Bernard and his wife Eleanor, daughter of Clemency by Wandrith de Corcell, [Curia regis Roll no. 162 (Hil. 43 Hen III), m. 21] for Peper Harow as having been settled on him at his marriage with Clemency."
