Thank you for the information on this Friederich AUERT. He may be the one I am looking for, but I cannot be sure yet since I only know the approximate years of his marriage in the US, 1855-1865, nothing more. The date of emigration is about right. But he may be the Friederich AUERT who settled in New York while I am trying to find one who settled in Kentucky.
Do you know the location of Wiche? Is it in Prussia?
