Thomas Barlow - He has a badly mangled tree above him

As always, it would be most helpful if you could be explicit in your post about which changes to make. For example, since you've already determined which set of parents can't be correct, it helps to link to those exact profiles in order to save us from repeating the effort of checking out all of the candidates.

I've disconnected Thomas Barlow and Rose Nash, since they were the "parents" who died before his birth. Can you link to the precise other relatives who are incorrect? Thank you so much!

Most of them don't have dates, so it's nearly impossible to figure out who belongs where. But...

This fellow Barnet Barlow is badly out of place, or has a bad birth date, or something else is wrong.

Timey-wimey ball has been sorted out, more or less.

Thomas Barlow II and John Barlow have been put in the proper time period.

Barnet Barlow turned out to be from a British line that came over later.

Also, the Thomas Barlow from Connecticut apparently had only daughters.
