Suffolk, other creations: Shortly after the Norman Conquest and Earldom conbining Norfolk and Suffolk was conferred on one Ralph the Staller [Staller was a functionary of some sort in the Saxon Royal Court]. At that time, and seemingly for nearly three centuries afterwards, no distinction was made between Norfolk and Suffolk for the purpose of conferring titles based on county names, the two areas being conflated as the land of the East Angles. In any case, with Ralph's death a few years after he was created Earl the title apparently passed back into the possession of the Crown, though within another year it seems to have been conferred on Ralph's son, called Ralph de Gael from a fief he held in Britanny. The second Ralph, Earl of this somewhat shadowy creation, rebelled against William I (The Conqueror) in 1075 and was stripped of his titles and lands. [Burke's Peerage, p. 2761]

Note: I think Ralph was 2nd Earl of Norfolk, after his father.
