I am looking for information on the family of Susanne Elisabeth Irgang who married Johann Dietrich Bertram Nehus. One daughter , Johanna Friedrika Georgine Nehus, was born in 1849 in Norden, Germany . Although Johanna was born in Norden in 1849, the family was residing in Hamburg Germany in 1867 when Johanna Nehus married Hans Heinrich Friedrich Singelmann.
