A picture from our own White County is on ebay right now. It is a picture with the inscription "16th Section Singing School" teacher Floyd Bradberry or Floyd Brobbery. At the ebay site there are close-ups of parts of the picture so you can see if any of your relatives are there. If it was a singing school it had singers of all ages. The item also says that the 16th Section Church is outside Beebe and McRae AR. Wonder which one of the men in the picture is the teacher Floyd.
Google gives the address of the 16th Section Church as 3387 Hwy 267 South so when I drive back down there I may have to check it out. But if you readers know about it, give us an update.
