This is the portion of the Zanzig study that is directly related to me, along with more of their spouses' families.
Fred had two brothers, one of whom died at age 32. His older brother, Joachim Friedrich Christoph (or Christoph), had nine children, several of whom emigrated to Chicago and then to Nebraska. Christoph's descendants are the larger branch of those known to be related to me and are fairly well documented.
Henriette's father was also Christoph--Adolph Christoph Zanzig. He was a tailor and musician. He and Christina Mohr, his wife, had seven daughters and at least one son. In 1856, Christoph, Christina and at least four of the daughters, along with assorted husbands and children, all emigrated to Milwaukee, Wisconsin. I am beginning to trace the daughters' families, and that's a prime reason for this sub-site.
Fred and Henriette didn't fare well in the New World. Fred died in 1861, five years after emigrating. Henriette remarried in 1862 to Carl Bohn, had a daughter, and was dead before 1869. Fred and Henriette's two boys were on their own in 1870, at ages 12 and 14.
I would be delighted to hear from anyone with additions and corrections to this data.
