If I were you Phil, I would scan them in the best resolution you can muster and post them on thegreatwarforum.org along with all the information you currently know on your relative..the GWF is free, but read the rules first and post it on the 'Soldiers and their unit's ' thread. The advantage of the GWFis that the experts on there may well know much in regards to regiment's and their various locations plus a knowledge of the terms and acronyms often used.
