Ron, I share your interest in the 7th and have sent you a picture of my great-uncle Bennett Whiddon. Transcription can be a tough job with the writing style and misspelled words. Frank starts out in Pickents County and was in Iuka, Corinth, Vicksburg, Bolton, Baldwyn, Greenwood, Lauderdale Springs (Hospital), Newton, Jackson Soldiers Home. I'll keep you posted as I go on the letters.

Both are my ancestors....are they part of your research?
