Proven

James Buchanan Parker and Sarah Parker
Besides the historical documents provided on James Buchanan Parker profile page, i offer this atDNA study to confirm the relationships between
Myself (Linda Sibley) Zimmerman, Raymound Parker, and Edith McBride

• Maternal relationship is confirmed by a 74 cM Autosomal Family Finder DNA match between Linda (Sibley) Zimmerman and her second cousin twice removed Raymond D. Parker through their common ancestor James Buchanan Parker and Sarah Parker
• Maternal relationship is confirmed by a 29.8 cM Autosomal Family Finder DNA match between Linda (Sibley) Zimmerman and her third cousin once removed. Edith McBride, through their common ancestor James Buchanan Parker and Sarah Parker

Further confirmation is proved through a triangulation between Linda Zimmerman, Edith McBride, and Raymond D. Parker, on chromosome one, Overlap on Chr 1, from Location 175,493,914 to 200,244,450, 24.7cM match for all three
