Poppa means puppet or little doll [Ref: McBride2]
The name Poppa comes from Dudo, who calls her daughter of Count Berenger. [Ref: TAF 24 Dec 1999]
What I have in mind is her (Katherine Keats-Rohan) article on Poppa, mother of William Longsword of Normandy, which appeared in The American Genealogist a few years back. Basically, she suggested that Juhel/Judicael Berenger was son of a Count Berenger, named by Dudo and William of Juminges, and that both this Count Berenger and William Longsword were maternal grandchildren of an Earlier Frankish Count Berenger. I have seen it speculated (i.e. by Guillotel) that Judicael Berenger's paternal grandfather might have been a son or grandson of King Erispoe, but there was little evidence with which to place him.
