Researching Dalton surname. Our Daltons came from Ireland in 1848. Mary (mother), John, Thomas, Simon, Francis, George,Patrick, all sons or grandsons. By 1850 they were in Schuylkill Co Penna. Most were coal miners. Do not know who Marys husband was. Mary was born about 1790-1800. Has anyone done any research on these people? Will trade all information I have. THANKS FOR ANY RESPONCES.
