Hi Robert -
contact Bryan Howerton via the Arkansas CWMB (URL below) and ask him if he has any info from the compiled service records for W.L. "Alex" Russell in the 11th/17th Ark. Infantry.
If yer lucky, it might give you confirmatory age/home info.
Tell Bryan I sent you...!!!!!
:-)
good luck,
y.v.o.s.,
Ken
