I recently was in contact with someone who helped me trace my paternal line back to 1750's Ziefen but it was mostly just names and dates. If anyone has more information about these people please let me know!
Heinrich Koch m: 27 Apr 1751 to Barbara Buser
Johannes Koch b. bef 16 Dec 1755 d: 14 Dec 1823 m: 1 Dec 1778 to Barbara Schäfer
Johan Jakob Koch b. bef 25 Sep 1787 d: 12 Feb 1843 m: 22 Mar 1813 to Katharine Hartmann
Johan Jacob Koch b: 16 Oct 1816 d: 14 Mar 1863 m: 10 Nov 1841 to Anna Buser
Jacob Christof Koch b: 15 Dec 1848 in Ziefen, Baselland, Switzerland
Jacob Christof Koch was the one who immigrated to the US (Ohio) presumably in 1867 (listed on the 1900 census). He married Mary Mast (from Germany) in 1871 (date also comes from the 1900 Census).
There are other children and info but that is my specific line. I would really love to find out when and how Mary Mast and Jacob Christof Koch immigrated as well as anything I could about the lives of these people.
Other names include: Tschopp, Degen, and Martin before the immigration and Titswood, Bebee, Trautman, Sommers, Fountain, Gonyea, and Adams after.
