MCMAHON Mathew; IRL; b.1836-1846 Seeking information on MCMAHON, Mathew. Unfortunately, this is the side of the family who dies young and didn't discuss their heritage! All that is known is that Mathew was married to DONAHUE, Susie (death cert. unclear may be DONOHUE) also of Ireland. Mathew immigrated to USA and had a family in and around Mendota Illinois. They had one son, McMahon, Thomas 1-3-1866 in Mendota, Illinois. Any information would be helpful. I know this isn't much to go on but thanks for your time in reading my posting.
