Alice, we need to compare what we know. I can not go back further than Grandpa's grand father and grand mother William and Hannah Dewhurst. Grandpa's father, Joseph Washington Dewhurst(1849 or 1850) had two sisters, Martha Anna(1843) & Mary Elizabeth(1845). Joseph served in the Civil War at the age of 15 or 16. He and Ida were married 1875 or 1874.They had 4 children Dwight (1879),Joseph C.(1881) & Rudolph (1890)the other child was not listed on the 1900 census and I do not know when or what only that it was born and died.
