Research notes
~ OSBERN DE BOLBEC, father of Walter Giffard I of Longueville per Jumieges (GND with Robert of Torigni's additions; taken up by CP 'Buckingham' and Keats-Rohan, Domesday People). Graded ~ not ✓: the filiation rests on the same 12th-century Torigni layer as Beatrice de Warenne's Gunnor link, and is graded the same way deliberately (symmetric skepticism). His own father unknown. ||RESEARCH-FLAG|| FRONTIER - evidence stops here. Added 14 Sep 2026.
