Many of my ancestors were said to be of Scotch-Irish origin and immigrated to the United States between 1700-1800. The McKEE family who claim they were Scot were in South Carolina by 1740. The DIXON family also settled in South Carolina early. The GAMBLE and KENNEDY couple came from Monaghan County, Ireland by 1800 to Pennsylvania? Were they originally Scot? The DIMOND family were in Pennsylvania by mid 1700's. I cannot find any Irish records and these families seem to have come through Ireland at least for a time. How can I find my way back to Scotland if I cannot find Irish records? Any help on any of these families appreciated. Thank you.
