I don't recognize any specific names that you listed in your post, but I am interested in the Barksdale family.Have you come across any Purnells (Parnell, Pernell) in your research on the Barksdales?A Purnell family Bible includes the following Barksdale entries:
William Barksdale was born December 6, 1793 Ann Barksdale was born October 15, 1793 William Barksdale was born November 28, 1837 William Barksdale died May 19, 1856 age abt 63 William Barksdale Purnell Senior died September 16, 1839 William Barksdale Purnell was born August 19, 1840
There are other entries, but these are the only Barksdale entries.
The Barksdale and Purnells came from Abbeville County, South Carolina about 1820 to Lawrence County, Alabama and then down into Marion and Lamar counties, and across the line into Monroe County, Mississippi.William Barksdale served as administrator for William Parnel's estate as indicated by records filed in both Abbeville County, SC and Lawrence County, AL.
There are also connections to the Robinson (Roberson, Robertson) families both in South Carolina and Alabama.
If any of this information looks familiar, please let me know.
