Oh my goodness - THANK YOU! I've been going nuts trying to find that info. I can't begin to express my gratitude!

Could you please explain to me what "dtd" and "n.d." mean in those abbreviations?

Also, do you (or anyone else) know why they list him as "Company D/I"? I've been trying to figure out if he transferred from D to I, but the way that is phrased makes me think the two companies were merged. However, the info at web.archive.org/web/20080116221101/http://www.tarleton.edu/~kjones/wilcox.html about Wilcox's brigade clearly lists them separately:

* Co. "D", Lauderdale Rifles (Lauderdale): J. Butler Houston (resigned, 29 Aug 61); William C. Reeder (promoted to major,
26th AL Regt); James M. Crow (wounded, Gaines' Mill; promoted); William James Cannon

* Co. "I", Calhoun Guards (Lauderdale): Edward Asbury O'Neal (promoted); Dougle W. Gillis (KIA, Williamsburg); Samuel
Spencer Ives (transferred to 35th AL Regt, May 62); John N. Chisholm (captured, Gettysburg; died as POW); Benjamin F.
Taylor (wounded, Sharpsburg; captured, Petersburg)

Thank you again, George! This is extremely helpful to a large group of us in my extended family.
