Carolyn, Sounds like we have the same family. My great-grandfather Richard did go to California for a few years after working in the Michigan copper mines, but came back to Michigan, where he lived the rest of his life. He was a mine "Captain," a superintendent of several mines in the Upper Peninsula of Michigan. He went back to Cornwall earlier to marry his sweetheart, Jane Nicholas. They had three children, William John, my grandfather, and two girls, Bessie and a sister whose name I don't have at my fingertips. I'm glad to find the name of Richard's brother, who was responsible for his coming to the U.S.Thanks!
