Thanks to the help of many people on this list but especially, Colleen, Pat, and Tami, I have filled in a lot of the blanks on my Scot ancestors. However, I have not yet found anyone who actually worked for Calumet & Hecla. I was under the impression that he was a McDonald but can't prove it. I do have a Lachlin McRae who was listed as a mining engineer on his Calif. Death Certificate. He was born in Canada and I have no idea whether he was ever in Houghton area. I know that other members of his family came in after the 1880 census. How likely is it that either man would be in the file cards at MTI? Are they indexed in anyway or would I have to pay to have someone pore over hundreds of cards? Marion
