Hi - I am researching John Pryor who married Francis Bingaman in Natchez. Francis was born about 1826 to Amelia ? and Adam Bingaman. Her sister Cordelia was born to the same two about 1828. Wondering if your 'Milly' is Amelia. John B Pryor trained Adam Bingamans horses and specifically Lexington. He moved with Francis and Cordelia to England and then settled and died in New Jersey. I have both Francis and Cordelias death certs and thats where I found Amelias name.
Let me know if you are still searching or can add any color.
