I went to look at Yerkes Cemetery, today. It is at 8 mile rd and Meadowbrook in Northville.
It is a little cemetery--the smallest one I have yet visited. It almost seems like a family cemetery. Although there are other names on some of the stones, by far the most common name in the cemetery is Yerkes. I took pictures of eight separate monuments with the name Yerkes.
Some of the stones are fairly old--some of them are falling down.
But other stones have been repaired or replaced, so someone is clearly taking care of the cemetery.
