Well, I just thought it was strange that there were so many Campbells in Windsor area; I figured they must be related. My best guess (and it's definitely a guess) is that Tam was born in Boston as some sources indicate and that he moved to RI with his family from whence he left to fight in F&I War with the Rhode Island battalions. This is off the top of my head as I haven't seen my records in a while, but I'm trying to trace down the 3 or 4 Campbells that were in RI, I think I'm talking about Windsor, RI but haven't had any luck.
