Margaret would educate and teach scripture to her slaves and plantation workers in the sitting room of the Great House. As her congregation grew, Margaret needed more space, thus began construction of the chapel in 1875. Margaret died in 1878 just before the chapel was complete. The first ceremony held in the yet unfinished chapel was Margaret's funeral service. In 1880, the church was moved to its current location, only a few feet from where Lewis and Margaret are buried. In 2005, St. Margaret's Parish dedicated a new 450-seat church building near the old building. Due to changes in church leadership and a steadily declining membership, St. Margaret's Church closed its doors in the Spring of 2012. The chapel can now be toured and the main church is being leased by First Assembly of God Fleming Island. To tour the old chapel call 904-282-3030.
