Interesting! To be honest, I had no idea there was more than one. The one I was taken to was indeed in Medford (I believe anyway, it was a long time ago and I could be wrong), I think on Elm Street, near its intersection with Woodland Road (where that small rotary is, past the skating rink).
I did recall why I thought of it though. I walked by an area in the Wyoming Cemetery where there are 4 or 5 Buttrick stones. I wonder if it's the same 'Buttrick'.
