I am NOT an expert on DNA results so will put this statement in layman's terms. DNA testing has been completed and posted at www.sekybrocks.com on descendents of Jesse Brock and Mary Osborne. NONE of these results reveal any Native American heritage in this lineage. mtDNA tests run on the sister of Jesse Brock (Mahala) also disprove any NA heritage. These results most assuredly put very serious doubts on the Chief Red Bird/Aaron/Jesse theories that have floated around the internet for quite sometime. The Sizemore DNA also reveals that there is NO kinship between any Sizemore descendents and Brock descendents...thus disproving the supposed marriage between Jesse Brock and Rhoda Sizemore. The Sizemore also does NOT reveal NA heritage. Joyce Gaston Reece
