Stonehouse Burying Ground is on Martin Grove Road, north of Eglinton. In 1819, Joseph Stonehouse comes from England and starts a family farm next to where we see this cemetary. The last burial was in 1912. Closed for over 100 years to new members. :)
Getting to it is easy, the fences are tricky unless you have your tetanus shots. Scraped my shoulder getting over. But no penetration, scratches or blood. It's fenced off so hopping the fence on the north side is your best bet. Just be prepared to land in some shrubs.
