Thanks all and sorry for lack of response, not much time at the moment.
Boo - Thanks for all the info. I had most of that with the exception of Mary b. 1889. It's great you have confirmed the info I had. At least I know i'm on the right path. I'm sure I checked for baptism records so Mary's children but i might go back and check again. I appreciate you looking at all this for me.
As you say, there are really only 2 records with Mary Bowen's birthplace and year of birth and they both differ which isn't helpful.
Sarah (b 1887) was my great grandmother. My dad thought she was Irish but all the records show different. I then found that her mother was potentially Irish so have been pursuing this for a while. I ordered a marriage cert and found I had the wrong Mary so then ordered Sarah's birth cert and now have what I assume is Mary's maiden name now. It looks like I may be at a dead end now!
