I have a little guide to the Angle cemetary. Mathew Angle sells them and has posts on this site somewhere I think. I also visited the Angle cemetery last year. There are some stones that are unreadable, and probably some missing. The book only showed this Sink that might be who you are looking for:
John T. Sink 1852-1934
No Martins. You can email me at email@example.com
if you would like more info.
