Audrey Becker's book "The Lives and Legends of the Ozark Yoakums" (what a great find) reports estimated birth years for Matthias' last two sons Henry (1753) and George (1755).
Becker also reports that the Botetourt County Court Order Books master index for Feb 1770-Aug 1808 includes the names of Henry and George as well as Matthias and other of his sons.
Is there someone more familiar with this record who can tell me (1) would appearance in this record necessarily mean that a person was an adult? and (2) does the reocrd identify in which years a person appeared, or simply report that they appeared between 1770 and 1808?
I am thinking that this record could help refine the estimates of birth years for later Yoakum sons.
