Descendants of Duke of Normandy 1028-1035 Robert I The Magnificent

Notes

Maud (Mabel) (Sybyl) FitzHammon C

Brian Tompsett of the University of Hull in England does not have 9 children listed for Mabel Fitzhamon at this time. He may change his listing and post the 8th and 9th child, who are
Richard FitzRobert
and
Robert FitzRobert

I have not found that Robert of Gloucester de Caen re married, so these children could be out of wedlock or from Mistresses.
