Maddy found these on her doorknob...no pigeon.
EDIT:
After finding out that there was a black piano player by the name of Blind Tom Wiggins who was around during the 1860's, lg15panda used the autokey "blind" on the code, and out popped this solution:
We figured out that Beanville = Beantown = Boston.Beanville - Holy Swamp - Above below the head - PU - Hurry!
Holy Swamp = Holy Marsh = Marsh Chapel on the Boston University campus.
We have yet to solve the the rest of the phrase.
