John Surratt's real parents?

[Gene C]

It would be interesting to know Mary's motives. Surely she was aware her son was a courier for the south, and that some of her overnight guest were couriers/spies too. How involved was she before the family moved to Washington? Did she become more involved in order to help keep an eye on her son's activities? Would she have ever become involved if it weren't for John? Or did he become involved because of her example?

Are there any notes or transcripts of the police interviews with Anna? Did Anna play any role in her brothers trial?
