Reposting on the Leu message board after a few years away and with a new email address. I have considerable information on their descendants and on Caroline's family, but know next to nothing about Michael's background beyond the fact he was born in Switzerland. According to their granddaughter, my grandmother, they met in Toledo, OH. Michael moved to Galesburg in Knox Co, IL, and either started a cobbler shop or got employment in one. After he was established in Galesburg, Caroline joined him and they were married. A few years later, they purchased a farm in Orange Township, Knox Co, IL. My father often said his Leu aunts and uncles were frequently called upon to sing at church services, weddings and funerals. And he told of one of the uncles who quoted his father Michael: "Der vomand und I, ve loved to sing together. I sung the low part und der voman she sung the high part."
I am willing to share what I have and would especially love to hear from anyone who has information about Michael prior to him immigration to the U.S.
