My great Grand fathers brother John Kinkel married a Johanna Dammann in May of 1860 in Le Sueur Minnesota. Her fathers name was Frederick and mothers name was Anna.
Johanna AKA Anna was born in Mecklenburg in Germany July 4 1843. This Frederick was born in 1805, and died in 1880 in Le Sueur Minnesota. Is that a relative of yours.
Thank you
Bill Kinkel
