Thanks for replying Jim,
Firstly, I have visited the website for company G, But I was mostly after some info on company A(2nd). I thought if I could find out which county it was recruited in, I could research it myself. There is an A.B Clayton listed from this company who died at Drewry's Bluff from memory, and I was going to see if I could turn the first initial into a name from looking at census/marraige records etc.
I'm working in China currently, so I lack some of the internet resources and book resources that others have access to.
Thanks again Jim.
