I have made an assumption that Lester is a son of Amos & Clarina, and thus belongs in this family group (needs more research to confirm).
In the 1880 Federal Census, Lester J. Remington is age 22, living with in Wilson, Gentry Co., Missouri, with Howard & Martha and their children. In 1920 Lester J. Remington is age 61, married to Mary age 49, and living with three children in the household in Maricopa, Arizona.
