My Clifford did not have a son Frank,sorry, and he now lives in NZ,not Aussie, however you probably have more chance with Gail, as at the moment i have found no link between my family and hers unfortunatley. She does have strong connections with Aussie so chances are if you get in touch with her she might be able to help you?? I have suspected for a while that i might link up with Gail somewhere but like i say, as yet we have found no links..
Have you emailed her to see?? If not i can get in touch with her for you and see what she thinks?? Good Luck, Karen.
