My father was born in 1901. His home was in Kuty, Galicia, Austro-Hungary at the time, later Poland, now Ukraine.
His first name was Moses, probably Moishe. At some point, his nickname became Munio.
Perhaps revealingly, after he moved to Vienna and became a successful businessman, he formerly
changed his first name (in the mid-1930's) to Maximilian, the first name of a former Austro-Hungarian emperor.
But his nickname always remained Munio, even after he came to America.
Happy to hear any thoughts about this or similar stories.
