Sandra:
After looking into this, I think you might be right about your roots. According to the 1850 Census, Salina was living with Alvah & Mary. Also, Rollin & Patsey look to be Alvah's parents.
On a separate note, thanks for the info about Flora Hunnicutt being the mother of Hettie Grace. I've done some research and found that information to be correct, I believe, although your dates reference a different Flora. Thanks for the tip. If I can be of further help, let me know.
Thanks,
Wendy
