My maternal grandparents were old time Ozona, Crockett county residents. They were Fayette and Jennie SCHWALBE and they were related to the PHILLIPS & LOCKHARTS. Would be happy to share info. My snailmail is Ann Carrothers 15250 Gray Ridge #716 Houston TX, 77082.
I e-mail from the genealogy library so sometimes my responses may take a while but I will always get back to you!
