I have found references that a Joan Somery was widow of Godfrey de Craucombe (Crawcombe) (Chaucombe?).
See:
https://books.google.co.uk/books?id=j5fKdA6BqNYC&pg=PA242&l...
Where it states Ebulo de Montibus married Joan de Somery widow of the King's Steward Godfrey de Craucombe.
I can't find much about Crawcombe but in 'British History online' about Watlington Manor in Oxfordshire it states it was leased in 1231 to Godfrey de Crowcombe with the honour of Wallingford Castle.
The question is:
1. Is this the right Joan de Somery that married Godfrey de Craucombe and Ebulo de Montibus? and did she marry these men?
This looks like it's this Joan de Somery. Joan de Somery
When you go to page 48, it says she also married Ebulo de Montibus. Ebulo de Montibus, Lord of Kitton
I'm back now! Curious that there seems also to be more than one Ebulo from your last link. The previous link does at least agree with me that a Joan married Somery and Crowcombe.
Godfrey Crowcombe was tenant of Watlington in 1231
It looks like the correct Joan was a de Bohun who married first a Somery and so may not even have a profile on Geni yet.
I've merged some of the obvious duplicates.
