The Answer is at our very own BCGHS website. Donny Anderson maintains The Blount County DNA Registry (independent of the Blount County Genealogical & Historical Society). The registry is the place to compare your test results with others if you have Blount County DNA connections. I do not have Blount County connections that I know of (yet) and I am no expert on DNA. I am just learning about it (like you may be) even though I managed to edit an article in the spring 2016 issue
Society members are working diligently to properly arrange and order family surname folders found at the Blount County Public Library. A digital inventory is being posted to the BCGHS Forum as the work is being completed. Currently, surnames ending in A - F have been posted to the Forum. Check the Forum often to see updated inventories!
