I am researching ancestors by the name of LUIG from Ösbern (near Menden). Several generations are listed in the Menden church records as "So and So Luig genannt Rüther" or "So and So Rüther" and I know the person is in the Luig lineage. Is anyone familiar with why this was done? I know in some parts of Germany (Emsland, in particular), a man took his wife's name if he married the heir to a farm. This doesn't seem to be the case with the LUIGs and it carries through 3-4 generations of 18th and 19th century LUIGs. Is it possible they were called by the name of the people they may have worked for? Any thoughts would be appreciated. Thanks.
