I stumbled onto this file from the Lincoln Financial Foundation on Mrs. Surratt. It contains a lot of newspaper clippings, some of which are most peculiar, such as the claim by Mrs. Surratt's "water boy" that Mrs. Surratt was at the tavern to greet Booth in person on the night of the assassination! There's also a piece about Alfred Gibson, who claims to have served Mrs. Surratt her last breakfast, a clipping about a Mrs. Dade who claims to have served Booth's supper at the Mudd house, and the revelation that Mrs. Surratt had her own "Poe Toaster" who regularly brought flowers to her grave back in the 1960's. Thought it might be of interest as I hadn't run across some of the clippings before.

And here's another file related to the trial of the conspirators. I haven't had the chance to look through much of the material yet, but the Lincoln Financial Foundation seems to have put quite a few interesting things online.
