I wonder if your relatives, Johann Friedrich Caspar Mahnke married to Johann Christine Dortig Paarmann could be my great-great-great grandparents? On my family tree they are listed as Caspar and Christina Paarman Mahnke. Christina was born in 1797 and died in 1891. I do not have any dates for Caspar. Do you have any more information about them?
