Thank you very much!! I will look closer at those particular PA counties now. Difficult to determine the migratin pattern as all I previously had was the birth of John's son Benjamin in Fayette County PA, his brother Robert (my GG Grandfather) born in Harrison County, Ohio in 1820 -- and then the family living in Holmes County Ohio in 1840. Add to that the DNA study indicating we are from Campbeltown Scotland -- but large hole in knowledge of when the ancestors departed Scotland and where/when arrived in America. My reply to Kellygirl may also be of interest to you. Appreciate your information very much! Willing to share whatever information I can find on Alexander family after our Scotland trip this Fall.
