What I have is basically what you have. John J was the son of Archibald. I am still reseaching your line. If you have any specific request, please tell me. I'll do my best to look it up.
My gg-grandfather was Manly Clinton Watkins. He was a fellow soldier of your Archibald and they probably knew each other. Companies usually have about 50 to 100 soldiers in them.
