My paternal grandfather Rudolph Dewhurst born 1890 had a brother Joseph C. Dewhurst born 1881 in Massachussetts. Their father was Joseph W. Dewhurst. Are we talking about the same man? I can not go back beyond Joseph W. Dewhurst's parents William & Hannah Dewhurst. William immigrated from England prior to 1843 but I have not found out when. If we are researching the same people could we share what we have?
