My name is Susan Merle Wright-McDonald. I am Thomas Henry's granddaughter. I don't know what information you would like to know but I am willing to help you in any way you would like. Grandpa lived in Grass Valley and I loved that he used to be a miner. He collected crystals from the mines and had them in his basement room we stayed at as a child when we visited. We loved the red dirt and snow of Grass Valley.
