My gggrandfather was William A.J.Dolan from Baltimore, Md. He served in the civil war and in 1879 he moved with his wife and children leaving behind other family members and settled and remained in Omaha, Ne. His father was from Sligo, name unknown. We know that William's siblings lived in Baltimore and that A.J.'s children were all born in Baltimore. A.J. was born in 1830 Baltimore. Is this info of any use?
