In case anyone is looking for descendents of Iffland from Magdeburg, Germany, I may be able to help.
Karl Iffland *1840 and Auguste Dobertin *~1845 from Magdeburg had 4 daughters and two sons: Auguste Emilie Alwine * 1869, Karl ALbert Emil * 1872, Emma Ida Auguste *1875, Emilie Luise Frederike *1877, Heinrich Gustav Otto *1880 and Auguste Ida Emilie. I'm a descendent of Heinrich Gustav Otto who had two sons: Heinrich Erich and Kurt Fritz. The first emingrated to Namibia and later South Africa, the second moved to West-Germany.
I myself am looking for descendents and ancesters to the Dobertin family from Magdeburg (also sometimes spelt Doberthin, Dobertien, Doberthien and Dobbertin).
I'd appreciate any information which you will please send firstname.lastname@example.org
