I have Robert William Best born 1857 in Madoc County, Ontario. This Robert married Sarah Ann Moxam on 22 Aug 1883 in Maynooth, Ontario, Canada. I have seven sibblings list for this couple. Perhaps this is the Robert that you are looking for. His ancestry is from Northern Ireland, aswell. Please feel free to email me directly at pkbest1956@yahoo.ca. I am a direct descendant of a brother to above mentioned Robert W. Best.
