Saint Evin is the patron saint of the O'Dempseys. The oldest Dempsey that I have been able to locate is an Arthur Dempsey m. Johanna Riley June 27, 1779 Old Swedes Church [vol. 36, p. 28], also John Dempsey m. Isabella Camper July 14, 1798 [vol. 87, p. 237.9], and James Dempsey died January 10, 1797 Kent Co. who left to Nancy Dempsey 500 Pounds.
