Casey Key is not part of any CDP.HistoryIn 1917, Alfred F. Wrede established the first post office with the name of “Nokomis” southwest of the original “Venice” post office. That same year, renowned orthopedic surgeon, Dr. Fred Albee, purchased 112 acres from the Sarasota-Venice Company. With Ellis W. Nash, Dr. Albee created the Nokomis Subdivision, by subdividing the property into 130 lots, with streets radiating from two inner avenue circles and the new asphalt highway, which eventually became U.S. 41. Right there on U.S. 41, Albee and investors built the Pollyanna Inn, a 35-room hotel.
