Thanks Joan for your checking some sources for me. It has been family "tradition" that Isaac was born either in Pottstown, Pa or Pottsdam, N.Y. The reason for us choosing to follow the Pa route was because everytime we asked our father what our family origin was he said "Pennsylvania Dutch". On the Ontario census that I have found Isaac on (1851, 1861 and 1871) his birthplace is given as U.S. We cannot find a death registration for him so we are deadend on that as well. The first concrete information we have on him is his marriage in Ontario in 1821. I appreciate any help you are able to give even if it is only to point me in some direction. I just wish I could go to Pa myself for a few weeks to search. Thanks again, June
