Take a look at the historical marker in front of 441 East Corbin Road. It identifies the Machin FARM. The owners of the house there probably know where the gravemarker is for Machin, Jr,
Note that the house at the address was built in 1942. That's waaaay too new to be the Machin HOME. The actual Machin house used to be across the street per this map drawn in 1807 by Machin, Sr.:http://iarchives.nysed.gov/dmsBlue/viewImageData.jsp?id=1851...
Attached are some things related to the land parcel at 441 Corbin.
Point A on the maps is 441 E. Corbin and Point B is Carlisle Cemetery.
The Machin Patent is #33 on the excerpt from an 1895 map of NYS by Julius Bien. It can be found here:http://www.davidrumsey.com/luna/servlet/detail/RUMSEY~8~1~26...
