Lewis Powell's skull and Joseph Gawler

[SpruceCreekHawk]

Not that it precludes John A. W. Clarvoe from being a Confederate agent, but in his Washington Star obit he was said to have served in the Navy prior to the war and he served as a a three-month enlistment in 1861 in Co. A, Battn. 6, DC Infantry, for which his widow received a pension. While Maryland looks likely as the state of origin for his family I can't confirm that; however, John A. W. reputedly was born on a steamboat between Alexandria and Washington, which provided him with his middle initials (and his mother one heck of an experience, if true.)
