The Bowe's are from my husbands side of the family. I don't know if there is a connection to your Mary as I have not spent too much time on this side. I assume that my Mary Jane Bowe came here alone as a domestic servant as many single Irish females did.
I did a little research on this Michael Bowe. His daugter Bridget married in NSW to George Darker. They appear to have lived in the Mount Pleasant, Mongarlowe River according to the Sydney Morning Herald 1881. George died 1886 in Queanbeyan NSW. Don't know of any connection to my Mary Bowe.
