We have been able to trace part of the the family back to Wilhelmine Knaak, b. 4-18-1843, in Lobsens, Posen, Preussen. Do not know if this is the same region of Germany. Some information indicates the parents were Christian Knaak and Eva Lochotzka. Wilhelmine married August Wilhelm Bruch.The family settled in central Wisconsin.We have not been able to find anything on the Lochotzka name and are not certain of the spelling. We do not know anything more about Christian Knaak.Any information regarding the family would be greatly appreciated.
