Notes:
Data source is Jane Weidman, 6009 Queenston, Springfield VA 22152
Jane had his name listed as Isaac Newton Mark Mumma, but I can find no evidence that he ever used "Mark".
Possible Error - 1900 census lists his birth as May 1858 which is different by one year from Jane's listing. Death certificate confirms 15 May 1858.

Isaac is recorded as going to Canada on 29 April 1912 to Kamshack, Sack. where he homesteaded property and began farming. He and Arabella are recorded as returning to the USA via St. Albans, VT on several trips in 1916 and 1918. They were returning to Auglaize county, Ohio probably for visits. On one trip, they recorded their son, William, as living in Kensau, Ontario
[Message from Ken who bought the land that Isaac had homesteaded in Canada. Ken wrote the following:]
-----------------------
He homesteaded the standard homestead here in Saskatchewan which was 160 acres (referred to here as a "quarter section" ). However, only about 60-70 acres were farmable, the rest being too hilly. I think he may have bought the land from a land development company, based out of Minnesota, which was advertising land in the Canadian west, because the quarter beside was also homesteaded by an American. I think by 1918, he had left Canada, as there was a different owner in 1919. I think it was a similar story for many, as the land in some areas around here was pretty harsh.
All interesting history.
