Dave, I don’t know why a reference to Company A, 4th Arkansas Cavalry was included in the genealogy information. That was a Union outfit, and the James Young listed on that roster survived the war. There is a strong case that J.H. Young, Company E, Dawson’s 19th was your ancestor. There was also a J.E. Young in Co. E, 19th, possibly James’ brother, John. Elisha might possibly have been a cousin, as he appears next door to James’ father’s household in the 1850 Census for Sulphur Springs TWP in the household of John and “Milla” Young. You can view the Camp Douglas Monument at:

There is a book published about the 19th entitled “The 19th Arkansas Infantry Regiment, Volunteers CSA” by Merrill Theo Pence.

You might be able to find it at Amazon.com. Good luck in your research.
