I was wondering since I have just started looking into my gr,gr, grandfather and families life in CA during the gold mining time, if anyone out there would have any good ideas which books might hold information about my ancestors? They went to CA from MO in the early 1870's and I have found them in Calaveras Co and also in Butte co and Shasta Co. I know they mined for gold and even had a claim on a gold mine. I don't know which one. Their name was CATES. (John Mathis or Mathew and also his sons, John Mathew and George Washington) I suppose I should try to find land records on them... I would be delighted to have someone point me in the right direction. Or share anything that might give reference to them in those Co.'s from 1872 to 1900's or so. I enjoy reading what all of you submit about the Gold Rush. Very interesting reading. Thank you. Sharon Moore [email protected]
