Jemima appears in the LDS Ancestral file, as a child of Christian Blocher and Sarah Spacht, with a birthdate of 12 Oct 1836. Since this is only 3 months after Christian's birth, and 8 years before Sarah's, it is either an entry error in Jemima's birthdate, or an error in attributing her to this family. The former seems much more likely given that her marriage date is in 1885. So I have changed the year of birth to 1861, but entered it with a question mark.
