Tuesday, May 7, 7 pm, at the Society.  Canandaigua history buff Bob Virkler will provide an extensive look at the disappearance of anti-Mason William Morgan from the Canandaigua jailhouse steps in 1826. Varying accounts of what happened afterward led to national controversy in the 1800s and have been hotly debated for more than a century. Open to all at no charge.
