Amy Alice Hastin was the daughter of William Hastin and Amey Hastin Hastin. Amey and William were related, Amey was born a Hastin and married a Hastin.
Amy Alice was born about 1807 in Rutherford County, NC and died after 1880. She married William M. Carter on October 18, 1831 in Rutherford County, NC. My research found 5 children of theirs. If you have an ancestry.com subscription my tree is called Hastin's of Virginia. More info there.
If you need additional help please let me know.
ps to all readers - If any Hastin/Hastings males are thinking about DNA testing I urge you to do so. FTDNA is one company who tests for a fee, currently about $168.
