On land bought 1875 by Joseph Gustav Rountree (1838-1 880) who planned house be-fore his death. Built 1881 by his young widow, Elizabeth Cornelia, with aid of her father, John Stillwell. The lumber was Florida pine, hauled from Rockport. Stone, quarried as caliche and hardened by the air, came from nearby Mulas Hills. Structure has withstood major storms and is still owned by descendants: Adele Rountree, Anne Marie Rountree Anderson and sons.
