I too believe that there is some sort ofconnection - I started checking the relationship when I found both Edmond Webster BLACK and Lafayette BLACK boarding with the BARBEE's in the 1860 Census of Leon Co.
The connections look as if perhaps they (fathers William and Hambright) are brothers - and the boys (EW and Laf) 1st cousins.I cannot prove the relationship with any documentation - only the coincidences which I have found.
FYI: Lafayette BLACK is buried in the Jewett Cemetery.His two sons Lafayette and Hambright and daughter? Teressa are buried there as well - as is Mary E. (Lafayette's wife) and others [total 8].I will gladly scan these Y2K Cemetery Project two-pages and e-mail to you if you don't have them already (the info is also now on the internet thanks to Cheryl Burks).I also have the web site for Leon Co. documented marriages of BLACK(brides & grooms) between 1885 and 1910 which shows Lafayette's kids (which you probably already have).
Will gladly share my tid-bits if you think there is some greater connection.
