Sandy, I forgot to mention Co. G, 40th Tennessee Infantry. This was also a Columbia County company. It was later transferred to Johnson's 15th Arkansas Infantry, and consolidated into Co. D of that regiment. The company had traveled to Memphis to join the 9th Arkansas Infantry, but that regiment was already full, so it was placed in the 40th Tennessee and served there for several months before being transferred to the 15th Arkansas.

Also, about a fourth of the men of Co. G, 3rd Arkansas Infantry, were from Columbia County. If I recall correctly, there were some brothers from Columbia County who served together in that company.

If you can't find the soldiers you're looking for, let me know and I'll check my files of companies organized in neighboring counties.
