Saw a documentary on ETV tonight on the Church of the Holy Cross in Sumter. It was more along the lines of history than paranormal. They did mention that Joel Ralph Poinsett was buried in the graveyard near the church. He's the person deemed responsible for bringing what we know as the Poinsettia to the US from Mexico.
Services are not being held in the church currently as it is undergoing some extensive renovation. The church site is over 200 years old, the building constructed approximately 1850-1852.
If you enjoy history,
here is an interesting article about the church.
