Ms. Ann,
Thank you. You verified some of what I just posted below.
Will add Pvt Buffington to the list. I need to do more research, but some of us here in SW Mississippi may have located the graves at what the Southerners called Wall's Bridge, and I guess Union called Tickfaw River, Miss.
I have a few friends in Philadelphia, Miss, and will have them start looking to see if Pvt Buffington has a marked grave.
Would greatly appreciate ANY other information that you may come across.

Thank you kindly,
Virgil Roberts
