Answer 2

Howdy! I did a few searches and I keep coming up with this one:

I did some poking around and found that registrations were not truly mandatory until 1874. Here is an excerpt :

"After Napoleon was defeated, civil registration was discontinued in many parts of Germany and replaced by parish register duplicates used for civil purposes, such as conscription. In Prussia, civil births, marriages, and deaths were kept again beginning in October 1874."
The website:

As records from that period were handwritten, human errors were everywhere.  

I did not see a tree on your profile to compare Jacob's parents to.
I wish you very best of luck in your search! Merry Christmas!  ~ Tami
