I believe the girl on the right is Anna Margaretha Schulte who later marries Josef Gerhard Hermann Lammers. The woman in the middle is likely her mother Maria Thelken.
Father: Josef Lammers, Mother: either Margarete or Anna Lammers, Children: Bermard Lammers, Tekla Lammers, Grete Lammers, Heinrich Lammers... other unknown.
Daughter Mary Anna Lammers not in picture. This picture was taken shortly after she had left for America.
