Family before Krause:
Saner Joachim, Occupation: Arbeiter (working man)
-.- Fried (abbreviation for Friedrich?)
First I thought the name is 'Sauer', because that does more sense to me and the 'u' often is not written as an clear 'u' but more than an 'n'. So, I'm not 100% sure about their last name.
Family after Krause:
Braun Mich (abbreviation for Michael?), Occupation: Landmann (farmer)
