My wife's mother is a descendant of THAT Henry Sibert (the one that married Catharine Lickliter, although we have reason to believe that the one who was the son of Johan Wendel Seibert also spent some time in Champaign County). The sons and daughters of Henry and Catharine scattered, so tracing them has been an adventure! The various Sibert and Seibert families in Champaign County (at least five branches) were actually all related, although they came to and went from the county at various times.
