When merging FindaGrave.com records my recommendation is to NOT merge with all the other family members. I think it is best to do each one separately. The reason for this is that the name-of-the-person-being-merged is saved in the Citation Text for the Source Citation and also for all people that the record is merged with. A Source Sitation looks like this:
See that last line: Record for Ida E. Lovelace? Well, that will show up every time you mouse over your sources for that person and can be VERY confusing when sorting out Sources.
Dear Ancestry… Wish it would save the name for for each merged Source in the Source Citation.
Those are just my thoughts. Yours?
