I am researching descendants of Friedrich Wilhelm Wulff (b.1833 d.16 May 1889). My grandfather, Theodor (Wulff) Wolf (b.28 Oct 1892 in Kiel, Germany)came to the U.S. after leaving the German Navy right before WW1. He had two brothers & four sisters that stayed in Germany. He was married to Hedwig Cropp (b.25 May 1899 in Hessen, Germany)daughter of Eduard Oskar Cropp (b.17 Dec 1865 in Buenos Aires)and Augusta Marie Heil (edb.08 Jan 1873 Wickstadt in Hessen). I have extensive records on the Cropp family to appx. 1400, but very little on the Wulf family.
Also searching for descendants of Johann Heinrich Jante, born in Gohlen, near Ludwigzlust, Mecklenburg in the mid to late 1700's.
Also, my grandmother was Nellie Koeppen. Her grandparents,
Johann Friedrich and Caroline Koeppen, emigrated to America on the ship Johanna Elisa from Hamburg to New York, arriving 29, June 1854.
