I just received some Breyer info on my family dating back to to the 1600's. In your query, the first listed descendent was born in 1828. I reviewed the names in the info I received against your names. The info I have is only from Luxembourg.Unfortunately, I have no info on any one in the US with the exception of my direct line which you are not part of. (as far as I know) The info from Luxembourg only has for the most part my direct line as well. One thing I did notice though they may or may not be of help to you. I have a Laurent Breyer born 10/29/1754 in Putscgeid, who married Elisabeth Wagener born 1758 , died 10/10/1830 Tandel. They were married 5/1/1779. The man who apparently originally had all this info is a retired school teacher in Luxembourg. He apparently is a genealogist as well. Suppossedly with a very large Breyer file. If you contact him, I think you should know, he only speaks German, so you will need a translator.
