Franklin B Hough's book A history of Lewis county in the state of New York published 1860 on pages 296 and 297 lists two companies that went from Lewis county, New York to the California gold rush. These two companies were called The Lewis County Mining Association and the Lewis County Mining Co. The Lewis County Mining Association was "organized at Turin, Feb. 10, 1849, consisted of 14 members who were joined by others, but disbanded in a few days, and only a few went to California. The Lewis County Mining Company fromed at Lowville a few days after the above date. "The constitution and by-laws, as published in the Northern Journal, Feb 27, 1849, never went into effect,...." "Perhaps fifty men from this county went to California for gold, nearly all of whom returned wiser but poorer."
I have found some of these men's names and will try and add them here. Some of the names were actually found in marriages listed in the newspaper for Lewis county. From these it appears that at least some of the group went to the Trinity area.
