The Atzerodts in the 1860 census?

[L Verge]

"I'm starting to think that a whole section of Charles County residents were missed in the 1860 census."

With the impending crisis of a civil war, maybe a good portion of Port Tobacco citizens decided to "avoid" the U.S. Census taker since they did not wish to support the U.S. in any way? Do we know who the census taker was for Port Tobacco?

Is John Leonard Smith the Atzerodts' Union brother-in-law who happened to be at Surratt Tavern on March 18, 1865, when George, Herold, and Surratt stopped in to hide the kidnap weapons? Is he also the one who was with the troops who arrested Atzerodt in Germantown?
