The document you are writing about must contain errors. However, this is a secondary copy, so this can be an explanation. Well, i'm sure the date I entered. According to the church records Marianna Deutschmann was born from Franciszek's father and Marianna's mother, née Werner, on January 10, 1849 in Stoki (parish of Pszczew), and was baptized on January 14, 1849 in Pszczew (document No. 1849/8). What is the number of the record from which you have a copy? I would prefer not to refer to "Ariernachweis" etc. documents at all, it is not serious and unscientific.
