I am doing genealogical research on Stephen Graves, married to Harriet King on 28 Feb 1829 at Blount Co., TN. They relocated from Georgia to Scott County Arkansas ca. 1855. From what I gather on-line, 2 sons John B Graves and Henry Mark Graves enlisted first in Co. D, 1st Regiment of Arkansas Volunteers and later in Co. I, 2nd Arkansas Mounted Rifles. A number of sites list: GRAVES, Henry M. - Company I, Sergeant & GRAVES, Mark H. - Company I, Private/Sergeant, as two people, but I believe them to be one and the same person. Input? Additionally Henry Mark Graves apparently received the Medal of Honor for the Battle at Murfreesboro. Input? Thank you for your time, J.R.
