Welcome to rootschat Michael.
I'm afraid we are not allowed to discuss living people here, so you will need to remove your and your mother's full names (initials are OK). I think it will be acceptable to leave your birth name though, as that name no longer identifies you. Someone else will advise if this is incorrect.
I can't help with your search, but I think this might be better on the NZ board where you should get some help. I will ask a moderator to move this for you.
After you have made a couple more posts (even just replying here a couple more times, will be fine) then the Personal Messaging system will be activated, and anyone willing and able to help you can contact you via PM, so we keep the names of the living off the public forum.
Best of luck in the search.
