Angela Knight, 2001, California, USA

I am trying to find an Angela Knight from California, who is believed to be my second cousin.Her brother Michael Steven Barber (lives in South Africa), replied to a message I posted on the Barber surname board back in February. We had contact by email but suddenly all contact from him has ceased and I'm hoping that nothing has happened to him, other than he might have lost his email access!I have found out some more information about our ancestors which would interest him and I believe his sister Jean also knows some further info about the family.
Is there anyone there who could try looking her up in a 'phone book?Otherwise, if you know Angela, please contact me or let her know I'm trying to get back in touch with the family and exchange information!
Regards,
Fiona Wilson
