The Anna Marie Hansen born in 1850 you are talking about is my great great grandmother. Her full name really was Anna Christina Marie (Schmidt) Hansen.
So much more to share and if you are in St. Louis, I would REALLY love to get in touch with you. I have everything, even visited the old house that they lived in (it is still there on Lempe Ave. believe it or not).
