For the past two years I have been trying to make a connection to my ggrandfather Micheal Dillon, who was supposed to be born in the county of Galway and immigrated in the 1860's to Chicago, Illinois. He married a Margaret HART from Mayo and lived in Chicago until he died in 1900. He was the father of 9 children all born in Chicago. He may have been the brother of a Patrick Dillon who married a woman named Bridget. This is all I have been able to find in the U.S. Need help with information from Ireland. Thanks for any help you can give.
