Re: Mattis / Matthews from Ernestown Ontario
David Wilson Mattis 1879-1955 married to Susan Clark 1884-1958 are the grandpartents of my friend John Millar. I am working on his family tree for him. It seems that the parents of David Matis are James Mattis b 1851 and Cecelia Ann Orr 1852-1924. Cecelia was the daughter of William and Mary Mattis born in Scotland/Ireland. James was the son of James and Nancy Ann? Mattis. That's all I know. If you have more info I'd really appreciate hearing from you.
All the best.
