I am still looking for your "Childers" ancestor.However, I did find a scan of the orginal marriage record in the county book for his daughter, Martha E. L. Childers when she married S. P. Moore in Clark County, Arkansas on Aug 1, 1875.
The license was applied for on July 26 of the same year and recorded in the Clark County books (Book G, page 14) on August 5, 1875.
Martha's husband was from just over the state line in Memphis, Tennessee.
Perhaps you have already seen this or have it in your records but I thought I would provide it, just in case. I'll let you know if I find anything more.Perhaps you could share what you know of his immediate family, if there is more to share.Other children?
