"622. 20 Oct. 1297.  Quitclaim in fee from Bennet, son and heir of
Bennet de Blakenham, to Hugh de Sancto Philberto and his wife Alice,
Bennet's sister, and to Alice's heirs, of his manors of Etone Hasting,

of Etone Hasting and the chapel of Thormerton, with dower from the

Stevenson, Edington Cartulary (Wiltshire Rec. Soc. 42) (1987): 159].

"Judging from the chronology, it appears that Alice (de Blakenham) de
St. Philibert is the sister of _____ de Blakenham (daughter of Bennet
de Blakenham), 2nd wife of Mattthew de Lovaine.  The Lovaine couple
are ancestral to Sir William Bourchier, Count of Eu (died 1420),
husband of Anne of Gloucester, granddaughter of King Edward III.
Further information on the Blakenham family can be found in the book,
Suffolk Fines, by Rye."
