You're probably right. My only reference was the microfilmed records from "Baird's Cavalry" (M323-180) which listed him as "H. Le Keasler." I did not look specifically at his service record though... might've been more clues there.

I have since found a reference to a letter in the John S. Ford Collection at the Haley Library... where Maj. Kavanaugh ordered Capt. LeKoester's arrest in October 1864. I don't know the details.

I also checked Ancestry too. Didn't find him in 1850 or 1870.. by my educated guess is that name is probably a form of Lacoste.
