Milligan v. Milledge, The estate eventually became the center of the Galphin Affair political scandal involving prominent political figures such as George W. Crawford.
Galphin helped foster what became Silver Bluff Baptist Church in South Carolina. Located on his plantation, it became the site of one of the first black churches in America. In 1773 the church was formally established as a Baptist church with a black congregation. David George, one of Galphin's slaves, was ordained there as the first black pastor in America. George, with help from Galphin's children, learned to read and write using the Bible and ultimately helped the congregation grow from eight to more than thirty just before the American Revolution. In 1779 George and around ninety other of Galphin's slaves joined the British side in the hopes of securing freedom.
Today, some 3,000 acres of Galphin's original property encompassing the trading post and plantation are maintained as the Silver Bluff Plantation Sanctuary by the National Audubon Society.
