I read your post, and although not related to the Sanders who are posting here, I have a William Sanders who was Born in England and immigrated to the US in the 1890's. He entered through the port of Philadelphia and obtained work in the coal mines of Western Pennsylvania. According to the 1910 census, he was born in England but his parents were born in Ireland. His wife was Catherine (Kate) although I have been unable to find a maiden name. His three surviving children were Margaret Jane, William and Dorothy or Dortha. Do any of these names fit in your genealogy?
