I agree with you 100%, without the participation of more men in the Carroll DNA Project comparisons can't be made. As more Carrolls enter into the database the better the results. Carroll men interested in genealogy and getting over their brick wall just can't hope that some other Carroll will come along and do it, they must do it.
I am a descendant of the loyalist Thomas Carroll who left the United States abt. 1783 and came to the Bahamas. I want to know his family connection and with DNA sampling we can. Myself and several other interested family put together to pay for a test. We have our results but the participants are low and as long as it stays that way it will most likely be a long time before we connect. This would be the same for others.
