We are trying to prove CSA service for William M. Rockwood, interred in Cedar Hill, Vicksburg.

Here is the information on his grave marker:
William M. Rockwood
Born Mar. 1, 1838
Died Sept. 26, 1878
President, Howard Association
Erected by his friends

He is in the Mississippi Confederate Graves Registry and is shown as being in the 28th Miss. Cav.; born and died in Warren Co., Miss.

I find lots on info on his later life and his obituaries on the web, but no mention of any service.

The usual sources have been checked. Will check the Confederate Veterans magazine next.

Any assistance is appreciated. /Anna
