Note: Since I’m updating things, I decided to revive this thread that we worked on last year. I still find the different signatures of the conspirators (and others) to be interesting to see.
Signatures of the Conspirators:

(From Mary's letter to John Nothey. This letter and signature were actually written by Louis Wiechmann, not Mary.)

(Probably signed by his secretary at the Baltimore Steam Packet Company and not actually John Surratt.)

(Signed Jno. Harrison Surratt)





(From the "Sam" Letter)


The only signature we are missing is from Michael O’Laughlen. We know he took an Oath of Allegiance but where would it be?
Poems written by John Wilkes Booth and David Herold while on the run:
"He put aside the dainty bribe
The little proffered hand
Albeit he held it in his thought
The dearest in the land
Not sharply nor with sudden heart
But with regretful grace
Meanwhile the shadow of his pain
Fell white upon his face
Dark daughter of the Sultry South
Thy dangerous eyes & lips
Essayed to win the prize and leave
Dear honor we Eclipse
She shyly clung upon his brow
He stayed now at the door
I could not love thee, dear so much
Loved I not Honor more.
Adieu, forever mine, my dear
Adieu forever more!"
The handwriting of the first poem matches the handwriting in Booth’s diary:

Does anyone have any other signatures they would like to add to our collection? And remember, the first person to find O'Laughlen's gets a gold star!
