Louis is my great great great grandpa. his Mother Katie Remarried a man by the name of Bruin. Her husband Fritz(Fred Jr.) Remarried also as far as I can tell as he has surviving family still in Le Mars, Iowa. Fredrick Sr. Started the Lutheran Evangelical church there so I would imagine that would be a good place to start looking for records. There was another Louis Born to Christopher(Fred Sr. brother) in Mt. Morris Illinois. which is where the whole family first settled before Fredrick moved to Le Mars.
