I checked on a people search web page called Anywho.com. I just typed in Richard Gardner in Oregon. Granted you can't be sure this person is still in Oregon, but if you haven't looked already, that would be a good place to start. Anyway, there are about 9 Richard Gardners, and one of them is a Richard A. If I were doing a search, I'd take a chance and give this person a call, the worst that could happen is that it isn't the right one, but the best that could happen is that it is the right one. Good luck!
