I have a relative that came to America about 1870, Margarethe Fensterer. She eventually married a Habenstein and then a Meuller. August Habenstein b 1842, Margarethe Fenster/Habenstein/Muller. b 1848. Fensterer is Magarethe's maiden name. Can you provide any light on the Fensterer family? I am looking for siblings of Margarethe's.
Would you like to share trees? It sounds like you might cover her as a child.
