This isn't a timely response, so hopefully the email address this will be sent to is still good.
Herman and Lizzy had 8 children:John, Mary, Ann, Charles (Charlie), Adelaide, Catherine (my grandmother), Louise and William (Bill).John, Catherine (called Kit), Louise and William were the only ones who married.Only Catherine and Louise had children.Catherine married Albert J. Miller (also from Fort Madison) and they eventually moved to Kankakee, IL where A.J. worked for the New York Central Railroad.They had 2 children:Elizabeth Jane (my mother) and Ruth.Louise was married to a gentleman named Sinclair (forget the 1st name right now; perhaps Al) and they had 1 daughter, Lila.
Only 1 of Herman and Lizzy's children remained in Iowa and that was Charlie.He continued to live in the "family" home with Herman and after Herman died, remained there until his own death in the early 1960's.Both Charlie and Herman ("Gramdpa Tieken" as my mother called him) were volunteer firemen in Fort Madison and Charlies was also the game warden for some period of time.
