Hello
I've already contacted one curator and see that there are a number of curators operating in this area as well as numerous other people and it has become a mess so I thought I should consult as some sweeping changes will need to be made and there is conflict between popular sources and little help from contemporary sources!
One fairly simple change I think we can make is that this profile, Geva d'Avranches was an illgt. child of Hugh "Lupus" d'Avranches and not daughter of his wife, Ermentrude.
I would also like to split off most of the other offspring from Hugh "Lupus" as he and Ermentrude only had one son, RIchard, who drowned in the White Ship disaster leaving perhaps 2 or 3 illgt children only besides Richard.
