Both Lloyd and K-R give the de Tillys as originated in Tilly-sur-Seules,
Lloyd with a [?].
Lloyd indicated that Geoffrey de Mandeville gave the manor of Wonford,
Devon, to William son of John, in marriage to his dtr, and that Henry de
Tilly hheld it for life. His heirs were in Normandy. William was the
father of Henry.
In DD, p 735, William is the son of an Otto not a John. Otto de Tilly had a
brother Roger. Otto married Mabel, the dtr of William fitz Raven, and had a
dtr Dionisia who married Henry fitz Adam de Neufmarche. William fitz Otto de
Tilly was the father of a Ralph, Roger, Otto and Thomas.
Is there a resolution of the conflict?

Note: I am not at all sure that the John & Otto spoken of above are the same persons. The William son of John, mentioned by Lloyd, "gave land in Castrum Tillei to Bayeus cathedral before 1153", and is therefore born much earlier (bef 1132, possibly well before) than I have William son of Otto. In fact Otto and William son of John might have been brothers.
