I forgot to add Maria is also called Mary and Marie. She was 44 in the 1920 census. She died 24 Aug 1949 San Fransisco California.
There is a Sister Minna, Uncle Pankratz (Pankrautz ?), Johann & Anna Buschmann (Address from a letter written in 1908 is: Elbing West Pruessen Germany Holl. Chaussee 30 Barake 6)
I also have a picture that was labeled on the back as "Buschmann Family" that shows Maria, Three older ladies that could pass as sisters, one Gentleman, two girls, two boys (one boy is in what looks like a Russian Kosovorotka Shirt) and an infant.
