The Raibles are on my husband's mother's side. It seems that every Raible I've ever come across goes back to Wurtenberg. I don't know anything about Pius' siblings or parents. I just know that he emigrated in 1881 at the age of 17. He traveled to Chicago & stayed there the rest of his life. I guess we don't have answers for each other, but let me know if you ever make a connection.
