Sources for Parentage of Robert de Ufford

I've disconnected from Sir John de Peyton, of Peyton Hall & Lady Agnes de Peyton (born Clemence)

As you know, http://fmg.ac/Projects/MedLands/ENGLISH%20NOBILITY%20MEDIEVAL2.htm#... has nothing to say about his parents.

And for his daughter Alice Ufford

Is there any evidence this Suffolk man was a Justiciar of Ireland?

I think I have found an originating citation for the Peyton connection; it looks to have been particular editions of Burke's?

See http://www.acvancestors.com/g1/p1604.htm#i48103

I've put back the connection. I'm unsure of the parents but I am sure of the brother

Sir John de Peyton of Peyton Hall in Boxford, who lived in the reign of Henry III. and was the ancestor of all the families of Peyton, had a younger son Robert, who was called De Ufford from his lordship of that name near Woodbridge in Suffolk, and was sent to Ireland as Justiciary in 1269* ' to settle and pacify Erin.'
