I don't know specifically about your family but as a general starting point for your Devers.They went by Dever and a variety of other spellings and came to Maury county TN in 1807 from Virginia. THis is an early note that may give you a little background: Charles Dever signed a petition in August of 1807 of petitioners to form Maury County, TN
