Hi Don:
My wife Joy (nee Odom) is related to Mattie Turner and may be related to the William Odom's you are searching for. Unfortunately, I only go back to Edwin Odom 1798-1870 married to Tamar (Tamer) Unknown 1798-1877. Do they tie to your William?.
If so will be glad to fill you in on my wifes ancestors and the info I have. Part of her family was from Anson, NC, Spartanburg, SC and Little Rock, AR.
Hipe to hear form you.
Marshall
