Who was Mabille of England

Terry Jackson (Switzer) I went ahead and finished the remaining merges for what it's worth. It may provide additional information for someone...

I recommending disconnecting (orphaning) but not deleting.

I looked in "British Kings & Queens" by Mike Ashley and "The Lives of the Kings & Queens of England" by Antonia Fraser--
both didn't mention a Mabille/Mabel by name, but did say that Henry I had 25 illegitimate children.

Henry I had an illegitimate son by the name of Robert Fitzroy of Caen, Earl of Gloucester: he married Mabel (d. 1157), daughter of Robert FitzHamon, Earl of Gloucester.
Does that shed any light on what you are doing?

Alternatively, Henry I's 18th illegitimate child, by an unknown mother, was named Eustacia; she married William Gouet III, Lord of Montmirail.

Does that help?

I have the daughter who married Wm GOet however I had no name confirmed. @William John O'Brien what source are you citing for this name?

I knew about Robert de Caen's wife Mabel already.

I think I've probably got all 25 children and hopefully in their rightful places. If you are interested in this area please take a look. I've yet to add all the 'about me' information or any sources.

My source is "Britain's Royal Families, The Complete Gengealogy" by Alison Weir.

All 25 are detailed. I will check against yours when I have a chance.
