Hi Paul, my 4th greatgrandfather was Thomas Bowen who immigrated to Boston from Ireland about 1850. At some point growing up, I had heard that the name was Bohan, too, but I'm not sure if it was someone joking around or not. Our Bowen family lived in Roxbury, South Boston and the South End. I'm not sure what part of Ireland Thomas came from. His wife's name was Margaret Long. I also haven't been able to narrow down if he had any brothers or sisters. Maybe we're related!
