There is a DAVID family file at the Cayuga Owasco Lakes Historical Society in Moravia NY Address C-OLHS Box 247 14 West Cayuga Street Moravia N.Y. 13118 We searched and searched for a Mr. David in Syracuse and tried to find his roots. He too met up with a brick wall. We collected every bit of information on Every David in Cayuga and some in Ononadaga county. This young man was caring for a parent who had Alzheimers.
