Yes Coombs, I have an Irish great great grandmother, no approx 1818 birth found for her, no maiden name on the marriage cert, nor is her mother named. Her husband's the same, born approx 1818, no birth info, on the 1845 Irish marriage cert. Only their fathers are named. Later Census info in England for both of bride and groom gives their birthplaces as Portarlington Ireland and Newry Ireland.
I since found out that the groom's mother was Sarah Annie, but still no maiden name!
I also found out from his military notes, that he was actually born in Moate, County Westmeath, again, but again only his father's name. This bridegroom is the same man in my earlier post, that died at sea in 1873, en route to Melbourne. By now widowed, but I still haven't been able to locate a death record for his wife. Ireland Grrrr!
