If you have hit a deadend in your research you may want to consider using Y-DNA. The Dealy Y-DNA Surname Group has been active for more than a year and we have successfully broken through several brick walls that have resisted all other attempts.
We have eleven total members with the surnames of Daly, Dealy, Daley, and Dailey. A DNA connection has been made between all of the above names with the exception of Dailey.
