I was working on this line in my tree and searching for documentation on the connections. I came across this PDF that lists the father of this Symon as Richard Hull:
https://freepages.rootsweb.com/~johnkbrown1/genealogy/jkb-ancestry%...
28. Richard DE HULL
27. Symon DE HULL (b.1230-England;d.1283)
It doesn't list a mother for Symon or any parents for Richard.
There aren't any profile notes with sources or documentation from this Symon back here on Geni. In fact, when you get to his supposed grandfather
Hugh, has two father's attached but no mother. Someone started at discussion about that in 2022 and I just posted there as well since nothing was ever corrected, still no sources or documentation.
So, as far as I can tell, beyond this Symon is questionable since Geni has his father as Robert and the PDF has him as Richard and there's nothing else at all on Geni to validate any of the names or connections from Symon back.
Thanks in advance for any help better documenting these connections, fixing the two-father situation for Hugh, etc.
