Question: Who is the paternal grandmother of Richard, Son Of William The Conqueror?
Sentence (from "Richard, son of William the Conqueror"): Richard is sometimes referred to as the "Duke of Bernay", as if part of his father's continental possessions, as in Burke's Peerage; this is a mistake based on the misinterpretation of a 16th-century inscription on his tomb, which was also intended for the Earl Beorn, nephew of Cnut the Great.
Relevant evidence: No
