"Sud Ple". I had an Uncle whom I have lost now as of two yrs ago, he had done a lot of work on the family tree. I have some information I will gladly share with anyone interested. He stated shortly before his death that he had traced all of the Blockers back to one point in Fayettville NC in the 1600's. The name was derived from the German Name "Bluecher" from the Heite German Clan. This clan was reported by him to be ancestors of the General Von Bluecher that had ties with Napolian. Many names used in my family where Haley, John, Micheal and William.
Locations involved in the information I have is Fayettville NC, Edgefield SC, Green County AL, Texas and Florida.
