You may be interested to know that Hubert's death record is on the Seeking Michigan site. I also saw a picture on Find-A-Grave of his stone. George listed Hubert as his father on his wedding certificate, but considering how far apart in age maybe it was more a matter of the relationship they had vs. listing Balthasar as his father. As far as their mother, Mary Kremer, is concerned, it looks like she may have died in 1905 in Portage Co. but I have no idea about her burial. Thanks for writing.
