Elizabeth, have you seen the book Joshua and his son William Riley Pyron ? There is a little about William Montgomery Pyron in it , but not alot. Say's his father may have been Thomas b.1790 , If so you may want to speak to Mary Bush ,that is her line, her e-mail address is JMbush@AOL.COM. If you don't have access to the book , let me know. Good Luck , Carolyn
