I am endeavoring to learn the grave site location of Walker Keith Armistead. This brother of Lewis Addison Armistead of Gettysburg’s fame was born in 1835. He served the Confederacy as a member of Virginia’s 6th Cavalry. He is recorded as dying on September 1, 1904 while a resident in Lee Camp Soldier's Home, Richmond, Virginia.

I appreciate any and all help. Thank you.
