The Hayes family, led by the matriarch, Mary Hayes Chynoweth (pictured below), accrued their wealth through iron ore mining ventures in Wisconsin and Michigan beginning in 1885. The family, Mary, her two sons, Jay O. Hayes and Everis A. Hayes (pictured below), along with their young families, moved to San Jose in 1887 after purchasing 239 acres and a house from Frederick Tennant. Their first mansion, a 22,000-square foot 1891 Queen Anne Victorian with more than fifty rooms, burned to the ground in 1899.
