Hi, I'm sorry I do not know of the people that you are looking for, but you may be the person that I'm looking for. I have been googleing H. Kemnitz to find the person(s) that may have lived in our very old farm house in Rosendale,WI. I found an old lithograph baby gift tag/card with Mr. and Mrs. H. Kemnitz written on the back of the card. Please respond back, we have been trying to find out more about our house and its history. Thank you.
