Me again My John Kinzie had a wife by the name of Eleanor Lytle, but he also had a common law spouse by the name of Margaret McKenzie. They had 3 children that I know of; William, James & Elizabeth. However my John Kinzie dies in 1828 it would sync up with your William being born around 1890. That would be too long of time.
Anyhow, keep in touch. You have my email address. The family name of Kinzie is just not that prominent so we must be linked together somehow
