Valerie Williamson, a descendant of Anna Rosina Zierke Thalacker, has access to Anna Rosina’s family bible, which her father owns. She has posted a page of it on her Ancestry website. I wrote to ask her if there were other pages with writing and to let her know I have someone who can translate historic German documents (Klaus Kolb). This was her reply:
Yes my father has the whole bible, I will go to his house tomorrow and take some more photos of it, and see if there is more writing in it, and email the pages to you. I would for sure be interested in knowing where the Zierke’s came from exactly, I have not done any research on them myself, too busy with my Dobrinski’s! Thanks so much!
I’m hoping there are perhaps other notations about the family tree in there, or really any other notes made by the Zierke family.
