Have located a record showing that a Johann Gottlieb Ferdinand KLEINSCHMIDT married in 1843, Langkafell, Pommern, Friedriche Charlotte Sophie SCHWANN, who was born 19 October, 1823 in Langkafel.
She died 18 September, 1865 and was the daughter of Gottlieb BARTELT. Their known sons were Carl August and Johann Carl Robert, born in Hindenburg, Pommern. I think this may be a sister to Wilhelmine SCHWAHN who married Johan BARTELT in the same place and came to Wisconsin in about 1856. Would like to contact any descendants.
