A honest question please: How should anybody at Archion (which has nothing to do with FamilySearch) know, where she was born??
Sigh.
You don‘t even provide her name, her DOB, the name of her parents or the like…..
Archion has no(!!) indexed church registers which you can search by family name.
Instead you need to know the parish where a person was born, got married, or died and then you need to browse the available images.
In order to do so, you need to buy a pass / subscription.
Church registers for WEIMAR are available at Archion, while those for WEIDA are not so far.
Kind Regards
