Brian - You star! Thank you x
On another point, you mentioned in your earlier response to me:
My Grandfather's occupation is confusing @.@ On his marriage cert, 1911 census, death cert, he is listed as a fireman. On his son's (my father) marriage cert, he is listed as a seaman! So, I wondered, if at some point he worked as a stoker/fireman on the boats. The address he got married from is in the Dublin Docklands (76 Seville Place)
Thanks again for your time.
