Michael Saunders came to Manitoba about 1890 with his wife Mary and 7 children all born USA. He was a market gardener in what was then the rural municipality of Kildonan and is now a district at the north end of the city of Winnipeg. At some time between 1906 and 1911 he moved to the municipality of Ritchot, which is located just to the south of Winnipeg, where he continued to garden.
