I have an Orth family recorded in the 1880 Census at Magnolia Rock, Minnesota. John Orth's parents were from France. I believe he married Susan Biersdorf in France before going to the U.S. The family members were:
John Orth 53 born Prussia parents birthplace France
Susan 47 born Prussia parents birthplace Prussia
Peter 22 born Wisconsin
John 15 born Minnesota
Cartarine 14 born Minnesota
Luzia 12 born Minnesota
Joseph 10 born Minnesota
Mathias 8 born Minnesota (my husband's g-grandfather)
Philip 6 born Minnesota
I don't know if this helps. If so, please contact me.
