seeking William, Elisabeth, Joanna Keister, Prussia to Ohio
The 1870 US census of Whetstone Township, Crawford, Ohio, lists William Keister of Prusia, his wife Mary and Daughter Clara, as well as Joanna Keister of Prusia and Elisabeth of same in the same dwelling as a separate household.Incidentally, Elisabeth is listed as an "idiot" (that was the term used on the census form.)
Joanna was 62 at the time, Elisabeth 35, and William 29.This leads me to believe that Joanna was the mother.
How can I find out more about her in Prussia? Where, and when, and why?William, Mary and Clara eventually moved to Indiana, apparently without Joanna and Elisabeth; Clara is my great-great grandmother.
