I had Christmas with Kopp's which included Lenz in the 1950's and 1960's. I met my some mother's uncle’s sixteen children in the early 1960's. They were all very tall. 
         I finally start researching all lines in 1974.I was lucky my mother's mother had many articles including obits, postcards, dairies, and pictures. I found out that
Bertha Louise Lenz was born 01 Dec 1861 in Watertown, Wisconsin, USA from the articles.
I found there was another Bertha Louise Lenz on the 1880 census that said that she was
10 years old 1870. I found the records of German Reform Church, Watertown, Jefferson Co., Wisconsin, USA that has her brothers Franz Ferdinand (Frank) and  August Herman christening records. Also Wilhemina Kranzke married Christian Almich in 30 Sep 1861
and christening records  of Friederich Wilhelm and Franz Friederich Almich their sons.
I believe that Wilemina is a sister of Henrietta Fredricka Krankze. I believe that the
Lenz in the Watertown area come from the same area in Germany. The Lenz in Germany area
were sheepherders.
          They moved from Watertown to , Freeborn Co., Minnesota, USA. The children
