Grady Howell's For Dixie Land I'll Take My Stand, a three volume Muster listing of all known Mississippi Confederate Soldier, Sailor and Marines, has the following Crisp listings:
Crisp, Benton; cpl.; Co. A; 9th Regt. Infan

Crisp, J. B.; pvt; Street's Battalion Cav.

Crisp, William M.; pvt Co. D; 1st Battalion Infan.;(Brandon's)

Crisp, William M.; pvt. Co. D; 21st Regt. Infan.

Another source lists no Moses Crisp, but seven M. Crisp listings are made all for Tenn. Units. I'll be glad to give to you if you think they will be of use.
