The convention at First Unitarian was organized mainly by a circle of activists in Rochester led by Amy and Isaac Post, who had resigned from their Hicksite Quaker congregation in the mid-1840s when opposition to the Post's abolitionist activities was raised in the Quaker congregation. Several members of this circle had participated in the Seneca Falls convention, including Mary Hallowell, Catherine Fish Stebbins, and Amy Post, who convened the meeting at First Unitarian. Some of the organizers of the Rochester convention were also associated with First Unitarian, including Hallowell, Stebbins and Post.
