Ernst and Katharina Mueller moved to Calumet County from Sheboygan County in approx. 1870. They had a son Wendle. Katharina was a widowed aunt living with a nephew Oswin Mueller in 1900. Any one having info on these people would be appreciated. Where and when did Wendle and Ernst pass away? Ernst supposedly had a brother named Ernst Mueller living in Sheboygan County at that time.
