To Leslie: I am interested if you have the name of Claus Sr.father, in Germany. My branch of the Staacks descended from a Christian Friederich Staack in Neukirchen Germany. My ggranddad was the youngest of his children, I'm curious if his one of his older half siblings may have been Claus. My ggranddad was August Wilhelm, born in 1865 and came to Iowa in 1886. Please advise, if you have info. Thanks in advance
