My 2nd great-grandfather, Michael Maguire, might have fought in the Civil War. I have some evidence that he was in the Army from May 1864 to July 1864; he must have been badly wounded to serve so short a term. He was born in April 1846 at Coldfields, Moycarkey, County Tipperary. He married Catharine Sullivan in Boston on 21 Aug 1870. I found a Death Certificate that says he died of Pneumonia at 99 Gold Street, South Boston. The address is important because Catharine makes a claim on his Civil War service in 1890 and her address is 99 Gold Street! If anyone has any more information or another place I can look to find more about his Civil War service I'll be very grateful. All my information has come from ancestry.com, rootsireland.ie or familysearch.org.
