Re: So, some questions:
A) Do we yet have the correct James on Geni?
Good next step to build him, as we likely have his origin family in Rhode Island. So will do that and post it for review. And, also, double check I got the 5 kids families correct. I think I got stuck at Wallens / Walling, and a Catherine Blevins parent controversy.
B) After the children of "Old Bill" are moved or disconnected, should we keep "Old Bill's" profile around -- Isolated as fictional & Relationship locked -- so it can be used a parking spot for this & other documentation about this "new" information? (Along with fictional spouses, ...)
Absolutely. And the “three Bill Blevins” analysis is a really valiant effort, I’d hate to lose it, even if it needs some updating. Plus, this is complex work. Let everyone take the time to think it through.
... once we have this sorted out on Geni, I'll take a stab at retro-fitting FamilySearch (albeit no mechanism to "lock" such changes other than accompanying documentation).
And FindAGrave also. One can leave “flowers” and point to the Wikitree.
