My father's father's father was Carl [Karl] Wilhelm Gabel, born in Ranis, Thuringia, Germany on June 13, 1858. He and his family immigrated to Chicago, Illinois, in 1886. His father was Carl [Karl] R. Gabel, also from Ranis (area of Ziegenruck), Thuringia, Germany. Any ideas or help on how to pursue this further back in Germany. I don't read German.
