Is their any more clarity as of present time about this Roricon? Some sources online have his wife listed as a Thyra, a daughter of a viking Sigfred, who was then the mother of Ranulf and Ermentrude. I realize these are very old profiles with much speculation however this one drew my interest as of late.

"He married Thyra, daughter of Siegfried of Walcheren , with whom he had at least two children:
Ranulph (Ranulfus) de Crépon (c. 900–981) who married Princess Gunnor of Denmark. A son or grandson of this marriage, Herfast de Crépon (Herbastus), was the father (or brother depending on sources) of Gunnora de Crépon , first concubine in more danico of Richard the Fearless . Herfast 's son Osbern de Crépon and grandson William FitzOsbern were loyal vassals of William the Bastard . William FitzOsbern took part in the Battle of Hastings where he commanded the left wing of the Norman armies. Both took part in the Norman conquest of England receiving great honours and prebends.
Ermentrude by Crépon"
