1930's - Johann Bärnreuther, Miller and Burgermeister of Mengersdorf, lived to be 85. (The "Mein Vater" is in Margaret's hand.)
1930's - I don't know who the child is. The picture might be taken in the 1920's, 30's, or 40's. As bad as the picture is, Johann doesn't look like a very old man, so maybe he was around 50 (died in 1952) when the picture was taken, which would place the time-frame of this picture in the 1930's. Sounds about right. :o)
hmmm... If the picture was taken in the 30's.... then... this could have been taken by Konrad on a return visit by him and Margaret Meyer to Mengersdorf. If so, then it's also possible that the little girl in the picture is Brigitte (Meyer) Steiner. :o)
hmmm... That could be right as far as the time goes. The previous picture shows Margaret in the 1920's as a young woman in the door frame with the wall and steps needing repair. This picture shows the wall and steps repaired, maybe even showing off the "new" downspouts. :o)
