Atzerodt Confession

[RJNorton]

Here is where I am confused. Atzerodt stated:

"Kate Thompson or Kate Brown, as she was known by both names, put up at National & was well known at Penn House. She knew all about the affair. Surratt went to Richd with her last March"

I thought it was Sarah Slater who went to Richmond in late March with John Surratt. They registered at the Spotswood Hotel and Surratt used the alias "Harry Sherman." They were in Richmond for 3 days.
