"An Official Genealogical Heraldic Baronage of England" (Gerald Paget, typescript, 1957) records: His wife remarried Richard de Lucy, with whom she held the manor of Shifford, Berks, in dower, of the Barony of Basing, (Testa p.124).

"Testa" refers to "The Book of Fees" aka "Testa de Nevill", and the entry records: A.D.1242-43. Ricardus de Lucy et Godheud de Sancto Johanne, uxor eius, tenent manerium de Westsipford' de hereditate Roberti de Sancto Johanne, quod est de baronia sua de Basinges, nec facit scutagium.
