This is fantastic! I've found several names on this list that are in my family tree. Captain Gilliam Hopper is most likely Gillum Hopper according to some records I have. James Keith is likely my great-great-great grandfather, James T. Keef. He was the nephew of Gillum Hopper, and married the daughter of Isaac Milam (Milum) who is also on your list. I have various Baughmans, Flippos, and Pattons in my pedigree as well. These folks traveled to Arkansas from Tennessee together.
Kind of breaks my Confederate-loving heart since I was raised believing these folks served with the CSA or, according to family tradition, Missouri Partisan Ranger outfits.
I have some oral family history and extensive geneology if you or anyone else is interested.
