Mary is buried in St. George's Anglican Church Cemetery in Grafton (along Lake Ontario, just east of Cobourg, west of Colborne and Brighton, south of Vernonville). It is one of the oldest monuments in the cemetery and is directly behind the church. The headstone is for John Runnalls and wife Mary. Beside this monument is one for her sons John and William and beside that Thomas Coffey and Matilda.
I have found the information for Ellen's siblings incidentally as I researched her. I will now go back and see what else I can find - perhaps it will lead to some Runnalls/Hoskins clues.
Looking through the Trease website has helped me tremendously. It has given me incite on how I might look for information in other sources (besides census, birth, death records), pay more attention to witnesses, informants and such and track related and neighbor families more thoroughly. (Although finding Eddys, McMurrays and Broomfields living side by side for 4 decades and intermarrying had me thinking along those lines

I particularly liked reading the reasoning/proofs for assumptions - I'm going to start listing the same in my notes. I find when I go back I often forget why I listed what I did and where I got the proofs and have to take the time to search my notes and line it all back up again before I go forward.
I have photos of the monuments in St. George's Cemetery, but don't know how to share them here.
I will start a Runnalls thread now that I know a little more about how to navigate here.
Thanks again for all your help. I hope I have helped to fill a small space in your research. We are all very proud here to have roots in Cornwall and have a connection to the Trayes family.
