It is very possible that we are related. I come form Archibald Caldwell through his son Archibald McHenry Caldwell.
Do you have a gedcom?
I would like to see it if possible.
All of the Caldwells there are through the Patriarch John Caldwell-or so my family has been told.
A branch off is possible.
I am willing to share any info if we are connected.
