As the source for this profile is another family tree I would venture to say that there are errors that need to be addressed.
1. the mother's name according to the source tree is Alice Lovell whereas this mother is Alice de Courcy (de Courci)
2. Alice de Courcy is supposed to have had one child only with her first husband Warin fitz Gerold - Marjorie not Warin
3. Warin was fitzGerold (fitzGerald/fitzGerod) not Michel
I will be detaching the profile for reasons given but make record here in case more reliable sources come to light.
