Thanks for the "Families of Ancient New Haven" suggestion. I have actually been using this as my main reference source, and it is good to hear you recommend it. I have also been using "Samuel Blakesley of New Haven, Connecticut and his descendants" as a back up reference, although I have found several errors in it already. The church records of the time have also been a regular reference source for this family, however, even the church records have provided some conflicting information. In one case, the church records gave a baptism date that was two years earlier than the birth date. Someone pointed that out to me and we simply had to delete the reference.
I know the advice to contact profile managers is meant to be as polite as possible to other Wikitreers, but when I see poor GEDCOM generated template profiles with useless references that have been unchanged for several years, I just assume the profile manager has no interest in the family, or they don't have the time to do anything about it.
I have found one instance of an undeniably duplicate profile in this family, but for which the two profile managers could not agree on merging, and so the merge was rejected. I have dealt with these kinds of profile managers in the past and I now just don't bother wasting time contacting them other than to re-initiate the merge with references included.
I posted this thread because the Wikitree script told me to. It was apparent to me that nobody was working on this family based on the state of the profiles, but I wondered if I needed a new badge to continue. BTW, this Blakeslee line is my direct ancestry, and I was working on it to clean up uncertainties leading to other profiles.
