I wonder if the Austin you mention is the same as the Col. Austin Murphy South who was active in the KKK after the Civil War.I have a difficult to read article from a Montgomery (?) newspaper about him.His KKK activities were in N.E. Alabama.My grandmother Dora Angeline South Dillard has a brother Elmer Houston South b. abt. 1895.Their parents were Elijah Franklin South and Mary Frances Hankins.They lived in Fayette Co. Alabama.I grew up in Marion Co. (Winfield) and remember visiting my South great aunts and uncles.In case you would like to have more of this line:Elijah's parents were Ezekiel Asbury South and Nancy Adeline Stewart.Ezekiel's parents were:Elijah South b. abt. 1793 and Rhoda Andrews b. abt. 1800.
If you find info about Co. Austin Murphy, I will appreciate hearing from you.Surely he must be related to "my" Austin somehow.
