This is very interesting. I am a descendant of George McFadden and Amelia Jackson. I and many of their descendants live in the Ottawa, Ontario, Canada area.
We believe that George McFadden's mother was Jane Fraser McFadden (1796-1876). We have never been able to determine Jane's husband's name. Our information was that she was a widow when she came to Canada in the 1840s with her four children: Jane, Margaret, Mary, and George. It was in Canada that George McFadden (c1835-1904) married Amelia Jackson (1836-1916); they raised a family of 11 children.
Jane Fraser McFadden, age 75, is recorded in the 1871 Canadian Census living in Navan, Ontario, Canada with her son George McFadden and his wife Amelia. The three of them are buried in a local cemetery along with many other McFadden descendants.
I would like to learn more about James McFadden. As I mentioned, our family has not heard this name of James ,nor that he came to Canada and died in Canada. We understood that he had died before his widow emigrated.
