In our family history my great grandfather is the above John Marmaduke. I believe with a middle initial of M, perhaps for Meredith. He should be born sometime around 1860.He marries a Nancy Duncan and their son is Duncan Meredith Marmaduke born in 1890. They are divorced sometime after that and according to our oral history, he dies in a Denver Hotel sometime before 1905, when Nancy Duncan's second husband adopts his son. He is William C. Hunter, hence our name of Hunter. Although I can't yet place the Duncans in the 1880 census, I am pretty sure they are in the Kansas City area.Is there someone who can help me figure out and learn about this John Marmaduke?Thanks!
