I emailed the city administrator about the future of this cemetery. I have yet to receive a response.
There is a cross-road behind the cemetery named Gunn Road. We'll name a road after you, but to hell with the graves of your family. Wow.
I have put up a page of grave marker transcriptions (the ones I could read and piece together) and photos here: Gunn Cemetery. Below is a short video clip of the cemetery.
