I have been doing a new search tactic and looked at Masters Certificates at the time my Gt.grandfather was at sea. I found 3 certificates, 1 each for 2nd, 1st and then Master. The Master was issued 24 December 1892 at Newport. His DOB was 19 Jan 1859, which about tallies with 1901 census. Address given was 32 Faythe Street. Hight 5' 6", brown hair and blue eyes. My grandad was about 5' 5" with blue eyes. I am posting this in the hope that someone can connect him to their family and I can either discount him from mine or if I am really lucky, maybe I have finally struck gold. Desperate Anne.
The John Walsh in those certificates matches nicely with the family of John Walsh you identified as yours in Castlehill St. in the 1901 census. That is, except for the address?
Also, this John's date of birth on 19 January 1859 has a big implication for you. If this is correct them some of the births to John Walsh/Mary Furlong you thought were yours (ones in 1870s?) are too early to be those of your g-grandfather (he would have been too young). I also think there was more than one family with these names at that time - birth registrations seem to indicate multiple families with these names having children through the 1860s and 70s, while your ancestors probably married 1880 to 1882 time frame?
Separately, we share common relatives, but don't appear to be related ourselves. A great-aunt of mine, Mary Walsh (ca. 1882-1960s), married a younger brother of your grandfather, James, and had three children. The family moved to Liverpool around 1911, after being deserted by James. Descendants are by the name of Fleet and....? Would love to reestablish contact with them (one visited my grandmother in Tramore shortly before her death in the 1980s).
Are you the same person as yellabelly on another board?
