My Great great grandmother was Johanna Mahoney. She was married to Laurence O'Sullivan. They lived at Kilmurry Kinard and then Deerpark. My Great grandmother was Nora O'Sullivan and she went to New Zealand when she was about 17. When Nora was baptised her sponsors were Thomas Ashe and Ellen Mahoney. I have always believed Johanna was Ellen's sister.
The information you posted has made me get a little excited and am thinking that this is the same family. If you think so, I would love to get some more information on the family. Kind regards Christina
