In 1920, Carl Yunghans and wife Hannah were living in Vincennes, Indiana. Of the four Junghans (Yunghans) brothers, only Carl refrained from having children.
Carl was employed as a carpenter.
Reminder for those that have been following along, Carl and older brother Emil had changed their name from Junghans to Yunghans after moving to the United States from Germany.
Their younger brothers Otto and Paul retained the Junghans spelling.
