I have a death certificate for Bartholomew (Bat) Moriarity dated 4/14/1908 from Cook County Illinois. He was married to Johanna Galvin (I believe). The death certificate says that he was born 37 years ago (1870 or 71 in Ireland and had been in Chicago, Illinois for 18 years (since 1890 or 91). Hope this helps. I do not know if it is the same, since there were many Moriaritys in Chicago at the time.
