You are fortunate to be able to pin-point your CARROLL family back to a specific spot in Ireland.

Do you have a man from your family with the Carroll surname represented in the DNA Project? It would be good if we could get several lines back to Ireland. That eventually might be helpful to others trying to compare their profile to know what area of the country to search more diligently.

If your family has not been tested, I would like to encourage you to consider doing at least the Y-DNA37 test, and the Y-DNA67 test if financially possible.
