My Missing Schneider Relatives

My grandmother slowly lost touch with her Hercegfalva/Herczegfalva/Mezofalva relatives after World War II, including her only remaining sibling.   I'm hoping the following photos and information might someday help me locate any descendants still living in Europe (or elsewhere).  I'd be forever grateful if you could please e-mail me should know anything about these people.

 

Ignac Schneider Family in Stuttgart

I know that some of my grandmother's relatives settled in Stuttgart, Germany after being expulsed from Hungary.  The photo below was taken in the early 60's when my grandmother's cousin John Schneider from the U.S. visited his uncle and cousins there.  The fourth gentleman from the left is John, and I believe he has his arm around his uncle Ignac Schneider b. 1887 in Herczegfalva.  The other gentlemen are likely Ignac's sons Gottfried, Stephan and Martin. The boys names are Stephan Jr. and Martin.

 

Eva Schneider

The woman below is Eva Schneider, my grandmother's younger sister.  I have her birthday as being March 23, 1904.  According to notes I had taken when talking to my grandmother, Eva married a Miller and had a couple of children.  I don't have any of their names noted.   Grandma kept in touch with Eva I believe until the 1940s or 1950s, and then lost touch with her.   I have nothing to base this on other than what was happening in Hungary at the time, but I suspect she was forced back to Germany with all the other German-speaking inhabitants of Hercegfalva at the time.  Although this undated photo below appears to be from Budapest.
