I found the marriage of Philo A. Smith and Harriet A. Thurston on 8 Aug 1869 in Big Rapids, MI. Both were born in Bayham, Canada West. (Apparently Canada was "restructured" some time after that.) Philo's parents were Cynes Smith (born in Maine) and Meredith Cyrus (born in New York). Philo is buried in Highland View Cemetery in Big Rapids. That's just 5 minutes from Green Township. Martha House died 24 Mar 1914 and is also buried in Highland View. Her parents were Israel Thornwell and Lucy Redubon, all 3 from Ohio. Harriet Thurston Smith died 20 May 1929 and is also in Highland View. BTW, I found Philo Jr's birth in Green township on 3 Jun 1875, and his father's name is listed as "Frank", and both parents were born in New York. That is from familysearch.org. Well, we know that old records are sometimes inaccurate. I didn't check the birth records at the county clerk's office for births. Hope all this helps.
