Thanks Bernice, I have found those census records and I know that Michael c Allen also lived in the states between 1907 and 1912 . He came back to Ireland in 1912 married my great grandmother in 1918 had two children and went to live with his uncle Michael f Allen in Boston in 1920 . Ireland was going through a civil war at the time and was a very tough place to live. He listed his wife Christina as his next of kin when travelling but that is the last record I have of him. Thanks for your help and if I can help on the Irish side for you with anything please let me know.
