She is not mentioned in the 1857 census with the rest of her family members. She may have passed away, as did her husband in 1851. It's also possible that she remarried after the death of her husband and went to live with her new husband's family. She would have been only 46 years old, certainly young enough to remarry in Grimm. A copy of the family's entry in the 1857 census is included below to identify the names of at least her male children.

Identifying who her parents were and her ancestry is a complex task. There were no Anna Louisas born in any year in the 1798 Grimm census. This means she was probably from a different village. This means that to identify her, we would have to comb through all the village census records, cross-reference with the 1834 census, and find the one Anna Louisa who does not appear in the 1834 census with a family. It's a near impossibility to do this manually. Unless we find a descendant who has detailed private records, we will probably never know her last name at birth.
On the other hand, studying the maternal haplogroup of Louisa's living female descendants could help narrow down her maternal ancestry.
