George, was Daniel J. Pittman killed on 1 July 1862 at the Battle of Booneville? Was he in the 7th?

Reason I ask is that I am compiling a history of my family cemetery (Grantham in Lamar County). The oldest marked grave is that of Coonie Davis, infant daughter of Christopher Eddings Davis and Emma Jane Pittman (daughter of Daniel Pittman and Susan McColskey).
