Here is a beautiful, hiddencemetery and an active one at that! There's even a WoW marker (Woodmen of the World). I have no idea who the Smiths were as it is a very common name. There is also an Irving pioneer family here named Hill who arrived around the turn of the 20th century. This is a very interesting place to explore! Entrance is on Penn Street, turn on Maryland then right on Penn. Good luck!
Congrats TeamOxford for FTF!
