Hello,
I have the great book by Daniel D. Hartzler, "Marylanders in the Confederacy". In it is an extensive listing and it has a Lt-Col Thomas Boyd Edelin as serving in the 16th N.C. Cavalry. Whether it is spelled Edelen, Edelin, Edlen, etc, we are all from the same common ancestor and related.

Anyway, what were you wanting to know about this Edelen that served with the 16th N.C. Cavalry? Are you related or descended from him?
Later,
David Edelen
