Sara, The Lockers (Lokkers) were from Buffalo and Dunkirk, New York. The connection I have is that Aurelia Picard married a Lokker; but I donot have a date. Her father was Charles Picard, son of Pierre Alexander Picard, son of Louis and Marie Anne. It would have been about 5 generations back. My maiden name was Locker. She was my great-great-grandmother.
