Noab Harney Indianapolis Indiana

Like many novice researchers, I have very little information to go on in my search for my great grandfather, Noab Harney. He is said to have abandoned my grandfather's family when my grandfather was very young. My grandfather's name was Charles Walter Harney, born 1877(?) and lived most of his life in Indianapolis Indiana. Charles was married to Alma Thomas who died in 1919. They had four children, George, Charles (my father), Alma who died in 1918 at age four during the flu epidemic and Margaret.
Any information on Noab would be greatly appreciated.
