Some sources state his Oslac's was Sabd of Ossory 750 – 804, married to Wihtgar of the Isle of Wight, son of Cynewulf, b c720, but he was probably the elder brother of Osmod (c801 – 836), the Governor of Sussex and Surrey.
Sabd ingen Maelaithgen hails from Ireland, daughter Maelaithgen of Ossory 750 – 804.
I have the following references, pobably dubious:

Oslac, Ealdorman of the Isle of Wight
The lineage goes back to trish mythology.

Is there any historicity in all this?
