No, my husband's Daum's and yours may have been kin a generation or two back but Anna was born 3 December 1822. We have her birth record.(See posting from Leslie)
Anna's parents were Catharina Pehl and Anton Daun. Anton's parens were Christiano Daun born ca 1766. (note the German spelling with he n) and Anna Maria Deutsch.
If you know your Anna's approximate birth date and you think she was born in Germany you can write the Catholic Archives.There will be a $30.00 research fee and $10.00 per certificate.If you know her parents - send that information also.
