Identity Crisis

This notice appeared in Dublin in July 1781:

This is to certify that I, Daniel O'Flannaghan, am not the Person that was tarred and feathered by the Liberty Mob, on Tuesday last; and I am ready to give 20 Guineas to any one that will lay me 50, that I am the other Man who goes by my Name.
Witness my Hand, this 30th July.
Daniel O'Flannaghan.

Wrote Henry Sampson, "A man who can afford to lay seventy guineas to thirty that he is himself, and nobody else, deserves credit for his boldness, if not for his ingenuity."
