I cannot locate any death cert for a Harriet Lyman that died in Ohio 1908-1914. Harry was a widow and living with the Wenzes In the 1910 census.
Through the years, Adams Township had irregular borders but basically it was southwest of Toledo. If you check Phillip Wenz in the 1910 and 1920 censuses you will see Angola Road written in the left margin. In the 1920 census, the next families (after Phillip) lived on Holland Road.
Adams Township was annexed to the City of Toledo about 1964. Angola and Holland (Sylvania) roads are in the far southwest area of Toledo.
Detroit Avenue and Anthony Wayne Trail only cross at one point and run closely parallel for only several miles.
If I were to guess where Harry is buried it would be in Maplewood Cemetery, which is on the corner of Byrne Road and Airport Highway, maybe 3-4 miles southeast of where the Wenzes lived in 1920.
PS. About a half mile west of the cemetery is Wenz Road.
