"Robert, son of King Henry 1st, having proposed marriage to Osbeorht, daughter of Baron Fitz Hamon, she politely declined, for said she,—'It were to me a great shame, To have a lord withouten his twa name.'  His father came to the rescue, and made him eligible for husbandship by styling his pet 'Robert Fitzroy:' son of a king = (En) Fauntleroy: king's infant = Cree for MacRee, Basilowitz and Rene (roy natus).  Her name Osbeorht: glory, brightness, of the Ases (for her beauty)..."

J. M. Kemble says: "Of the seven sons of Æðelfrið, King of Northumberland, five bore names compounded with Os, thus, Oslaf, Oslac, Oswald, Oswin, and Oswidu.  In the successions of the same royal family we find the male names Osfrið, Oswine, Osric, Osræd, Oswulf, Osbald, and Osbeorht, and the female name Osðryð; and some of these are repeated several times."  Then in a note he adds: "Os, semideus, Gothic Ans: thus A.S. Oslaf, Goth. Ansilaibs.  This word is nearly peculiar to the royal (god-born) race of Northumberland, and occurs rarely in the south of England; and where it does it is rather of Jutish and Angle than Saxon character."...
