I have just pulled out all of my research notes.
Robert Ufford, 1st Earl of Suffolk
His Father = Robert, Lord Ufford (died 1316)
His Mother = Cecelia, daughter of Robert de Valoines (died 1325)
His Grandfather = Robert de Peyton (died 1298)
His Grandmother = Mary - she was wifwe to William de Say who died in 1271. But i have not discovered who she was exactly.
The name "Ufford" was taken from the name of the manor, in Suffolk, of Robert de Peyton.
Hope this is of help. I have more info if you want.
