Thanks for coming back to me. I'm afraid I don't know how to deal with a gedcom or how to send one in return. Hang on a while though. Although I am sure Mary Ann is George and Elizabeth's child your comment has made me question my own knowledge. I will retrace my steps and double check. After all Mary Ann is such a common name.
I will be back with my findings. If I am right a swap of sorts would be wonderful.
