According to an email, sent from a professional genealogist in PA, I am a distant cousin to Albert F. Caldwell. This geneologist would not show the specifics, nor the charts his work had generated. But, he did answer my burning question: Were the Caldwells of eastern and western PA related? Yes. Due to client privilege, he witheld the specifics. My guess is, we can both be connected to this Charles Swan Caldwell, from near Pittsburgh. Details, leads, specifics, and/or denials would be helpful.
