Carole,
Thanks for trying!
I really do agree with you regarding the level of difficulty, and the pitfalls of paying for certificates in the hope they are the right one's. In the same vein I am trying to verify Ellen's maiden name and a Dublin marriage in 1910 to grandad. I have applied for a certificate for the best match I could get, all I know is the 1911 census showed they had been married 7 months. If I am correct, Ellen's maiden name was Georghegan, as you discovered with post 1916 Liverpool marriages, you wouldn't believe how many Ellen's married an Andrew O'Brien in Jul-Sep 1910 Dublin. It may all be a futile exercise, as apparently grandad's second marriage so soon after my paternal gran died, caused a great deal of angst in the family. As my dad was only nine when his mother died, he was apparently significantly less than enthusiastic to get a new mother only a year later. This probably means few if any of the family remained in contact with Ellen, for as far as I know she had no children with Andrew.
Thanks again, if the certificate I have ordered throws up anything interesting, I'll let you know.
