Ferdinand Berg

I've been looking for Ferdinand Berg for a little while now.  He is the father of Otto Berg who married into my direct line.  All I knew about him was that he was born around 1844 in Prussia and he was married to a woman named Albertina. 

Yesterday I found him in several census records. He was born May 9, 1844 in Prussia and died 22 Nov 1945 in Fort Atkinson, Jefferson, Wisconsin. His was was Albertina Kutz (1850 - 1924). I was also able to find his parents, Martin Berg (1823-1864) and Ernestine Wilhelmine Hocker (1821-1905).  Ferdinand had FIFTEEN children!
