(births of children)
Immigrated with brothers Johann Martin, and Johann Jacob.
Michael Frey's death is estimated (fall 1786 and fall 1789) because he was not present for the Christening of his son Jacob Frey.
Michael and Dorothea Frey are parents of John (1777), John Martin (1779) Johann Michael (1781) and Jacob (1787). I am certain that the John Frey/Fry and his descendents are descended from this couple. Ref is the Trinity Lutheran Church Records vol I and II.
But, there is more than one Johan Michael Frey. And there is more than one Dorothy.
I believe it is Johann Michael Frey, born in Germany 10 Aug 1743. The reason is that he names his children after himself, his father, and the two brothers who came with him on the Brig Betsey in 1 Dec 1771 (there his name is Michael Frey).
2. Other thoughts by Dale Berger and Esther Forsberg.
This looks like the same Michael Frey that I have with a different wife and children. This LDS reference agrees in part.
There is no source for this LDS record either. A similar line:
involves the same John Michael Frye, born in Muddy Creek in 1745, and Dorothea Schmidt. But this Micheal Frye has different parents from Berger/Frosberg. He has 9 or 10 children. depending on the reference, and some of the names are the same: Catherine, Martin and Jacob. All of them born in PA. This ref gives the same DoB for Martin and Jacob as found in the records of Trinity Lutheran Church. All this family goes to North Carolina. And the wife, Doretha, is Anna Maria Dorothea Schmidt, almost certainly not the Dorothey Freyin who marries Micheal Frey at TLC and then marries Ruch in 1796.A different Michael Frey with nearly the same date and place of birth
