Grove School No. 8, Black Creek Township, Mercer County, Ohio, was located in Section 33, on the south side of what is now State Route 707, just a little west of Wabash Road. The school was taken down years ago.
On the 1888 Black Creek Township map below, the red arrow points to Grove School No. 8. The turquoise arrow points to what was the location of East Bethel Church. East Bethel Church is gone but their cemetery remains. The green arrow points to Wildcat School No. 9, at the corner of 49 and 707.

Grove School is also shown on the 1876 and 1900 Mercer County maps.
Below is a photo of the students standing in front of Grove School in about 1933. I have shown this photo before, and once again I ask if anyone can identify any of the children in the photo.

A couple of the students have been identified.
Front row: Melville Gehm is the second boy from the left and a Gause boy is the fourth boy from the left. There are several other Gause children in the photo.
Thank you to Linda (Gehm) Duff for sending me this 1933 photo, which includes her dad Melville Gehm.
I have previously posted three other photos of Grove School students, two of those photos (1930 & pre-1930) were submitted by Doug Roebuck, who identified a number of the students.
