He owned the 944 acre "Seaside Plantation" on South East center of the island and served as a Justice of the Peace and commissioner of Free Schools in the Beaufort District. He had this mausoleum constructed in 1852 for himself and his wife Eliza Fripp; both of whom died in 1860.
The mausoleum was constructed by W.T. White, a stonecutter from Charleston. During the war the crypt was ransacked possibly by invading troops. Currently it remains opened with a direct view into the crypts which are now vacant.
He also owned Tidalholm in Beaufort, SC. You can find information and photos on the Library of Congress site.
