"

Isaac's brother, Joseph (1803–1888), was also an abolitionist and had early differences with the Quakers, although they finally came around to his point of view. He encouraged Isaac T. Hopper, Charles Marriot, and James S. Gibbons when they were disowned by the Religious Society of Friends on account of their outspoken opposition to slavery. Joseph spent his whole life in the house where he was born.[1] Isaac Post died in April 1872. Amy Post died January 29, 1889. They are buried together in Mount Hope Cemetery in Rochester, New York.[citation needed]
