It sounds to me like we are talking about Frankenhofen near Ehingen.
I would recommend reaching out to Jutta Uhl
I am not sure if she speaks English; however, she is on the
Ehingen town council representing the Frankenhofen area and she also heads up the local town band and will certainly know whom to forward the request to (a local Heimatverein) or what files if any would be available. http://www.cdu-ehingen.de/index.php?ka=1&ska=profil&...
Just click on E-mail senden to send her an e-mail.
Hope this helps.
