Okay, I just found the note requesting my participation. Sorry to be late to the party! Inbox messages get to me faster than being tagged in a discussion.
First off, there was no merge on Rose's profile since January. However, there were non-merge edits done in May (parents were changed), in April (data added to nickname field), February (parents changed) and in January (child and spouse added). With this in mind, will the merge undo script still work?
Second, I can still follow the link to Erica's source. It says Daughter Allerton, by a second wife, married Mr. Newton and had a son, Allerton Newton, mentioned in the will. This is the same data that Donald is referring to.
Third, from the history of the overview tab, I cannot find any revisions that would have removed history from that tab. Sorry, Erica, if you made notes on the overview about the first name Rose, I surely cannot find them.
Last, regarding Angus' link above, "From Roots to Nuts," Isaac had a son named Isaac, born about 1630, who graduated from Harvard in the seventh graduating class and who settled in Virginia beside the NEWTONs.
I don't know a lot about Mayflower families but I do have some decent resources when it comes to early Virginia families. I will see what I can find on the son Isaac who settled in Virginia.
