http://search.ancestry.com/browse/view.aspx?dbid=6742&ii...This same family, of Fred Tecklenburg, appears in the 1900 census, where Louis is listed as born Nov 1877. The 1900 census indicated Fred immigrated to US in 1863.
He MIGHT be the "Frederick Tocklenberg" who immigrated to the U.S. aboard the SS New York, bound from Bremen and arriving in New York on 09/02/1863, which indicated he was from Oesede.
