Laura,
My g-g-grandfather is Michael Rhoads b.1804.
he married Elizabeth Wilt. b.1809. I recently found out that his father was George Rote b.1764 in Germany. His Grandfather was George Michael Rote b.1730 in Germany. Married to Elizabeth (unknown)
Does any of this add up to what you have??? It seems that this line (Michael) changed the spelling at his generation. I am willing to share all that I have.
