I would love to discuss this with you further. I have the same names in my family. I have traced them to a John Adler born in Haubstadt, and I know that he is related to a Nicholas Adler...possibly his father. I have found a Nicholas Adler who died in Haubstadt...however I don't have a direct link between him and John. It appears that their may have been two Adler siblings marrying two Emmert siblings and I get pretty confused on it all.
