No answers to postings in FL, MI and NC regarding identification of B & G Assoc. men. A good Google search online, led me to Col. John Probert Cobb's earlier in life picture in uniform along with his brother,CSA Pvt. Wm. Henry Harrison Cobb, standing beside their father, Wm. Donnell Cobb. The photo, located at the NC Archives & History is available for viewing online. Looking at all the B & G Assoc. images, if I had to guess, it would be #2 or #3 in that order as Col. Cobb would have been in his 60's between 1880 and 1890.
