My husband's great-great grandfather is George French Brigham (John-James-George French. He left Dunkirk and worked in Chicago and later, Sharon WI as the station agent for the Chicago and Northwestern. Three of his sons had very successful careers in the railroad. The family has letters written by Fidelio, Wesley, and James from San Francisco 1854-1856 home to Dunkirk to their parents and to their brother George French. They had a water business which supplied water to businesses and homes in San Francisco. I would be interested in anyone else descended from James and Fanny Risley.
