I may be able to help you with your Dolly Dixon, although my Dolly Dixon was not born in MO., she was born just across the line in AR. Can you give me a date of birth for your Dolly? Please contact me offline at Catdar@aol.com
If your Dolly is who I think she is then I can connect her to her parents and maybe figure out who the man was who fathered her children. I'll be waiting to hear from you. Thanks!
