Terry, Thank you for the help. I would think Martin would have mustered in with a Pennsylvania unit.However at the moment, I am at a loss to much more imfo. All I have is a copy of an obituary. I know he was born on 8/4/1831 and died on 12/24/1905. It does mention he served as a Medical Officer at various hosptals and Army Posts. I will keep looking. Again, I Thank You !!
