I have a merge which crosses the line between documented genealogy and speculative genealogy, but the duplicates already exist. It's a mess.
We have a Sarah Osborne Gatley with four husbands. Two of her husbands are named John Crew and the other two are named John Crews.
John Crew II (Crew-128)
John Crew (Crew-30)
John Crews(Crews-768)
John Crews(Crews-151)
Mostly they cannot be merged because they each have different parents, and here is where the documentation fades into speculation.
Why can't we just DISCONNECT ALL THE PARENTS and merge them into one John Crew or John Crews?
This eliminates three problems at once. First, it stops the speculation at John. Second, it removes the conflicting parents. Finally, it removes the duplicates.
