I know this is a few years ago, but I just started to look for information regarding Frank Kaspar. My grandfather was Frank Kaspar who lived in Cicero, and was married to Olga. He was the cousin of Frank (Mary) Kaspar. He also was a clarinet mouthpiece maker. I am trying to find information on his parents from Czech. They died when he was very young. He and his brother Gustav came to America in 1910.
