James Graham, Alexander Graham (his son), his son-in-law Christopher Hartsough and their wives in 1817. Never purchased land, but squatted it. Named Rochester after Rochester, New York, since many of the settlers headed to Rochester MI were from there, but was originally part of Avon Township.
Land was extremely cheap, and veterans of the War of 1812 were given cheap land. Instead of finding swamp in the area, there was great soil for farming that people took as well. As the population increased, as did the main downtown area.
