Ralph de Bingham, of Sutton Bingham, Somerset (descended from Sir John de Bingham, living temp. Henry I); had [Ralph], with a younger son (Robert, bishop of Salisbury, died 3 Nov 1246). [Burke's Peerage]
Note: Obviously the ancestry I have for Ralph does not quite agree with Burke's Peerage. John in my ancestry was born 972, which is a pretty Norman sounding name for that period. I think the birth dates in my lineage are a little far apart. John may have been born much later.
