Amanda Maier's great grandson Fridtjof Thaidens sent more family photographs! He also identified some of the people in the photographs in a previous post about Amanda Maier. If you haven't read it yet, make sure to read this post about her as well.
Amanda's father, Carl Edward Maier who like his daughter passed the "Musik-direktor" exam in Stockholm (1852). He was the son and grandson of a schoolmaster in Riedlingen in the former kingdom of Wuertemberg in Germany.
