My friend's grandfather lists his town as "Krutzy, Russia". On another document
it is written "Konze, Russia". The family always pronounced it as Kruche.

I'm having trouble finding it on the usual sources. Does anyone know where it
might be?

Alicia,

Most probably town Kraziai, Lithuania. "Other" known town names are: Kroz,
Kroze, Krozhe, Kruce, Kruz.

Another candidate is: Krucha, Belarus.
