Frances, I hope you will not be offended in my saying what I know about your family names. Perhaps you know this already. Sizemore is probably a Sephardic Jewish name--originally "Cismor", a Spanish surname. Your George Sizemore who was married to Aggie Shepherd--"Shepherd" is related to the word "Sephardic". I believe the surname BROCK (Aaron)-the English name of Chief Red Bird and the son of Reuben Brock--is Dutch. Some believe that Jewish traders/peddlars played quite an active role in the early exploration/settlement of the Deep South and Appalachia in the l700s and l800s. If I have presumed too much, please forgive me. A fellow researcher. Carolyn Funderburk bamagal50@ec.rr.com
