I am looking for a Bernard DONOVAN who emigrated to the US circa 1845 with a brother, Thomas(?). I am told that he and his brother split-up in NY and never saw each other again. Bernard worked for the railroad and died in 1898 Creston, Union Co, IA. Bernard married a Mary Ann MACKIN, possibly in NY state. Bernard and Mary Ann had about 10 children that all lived in and around the Union Co, IA area. I have no other info on Bernard. Any help appreciated.
