Legit German names are typically meaningless (Goebbels, Himler) or professions, Schmidt, Metzger, Müller, etc. (smith, butcher, miller) The exceptions are that Miller is a common jewish name due to intermarrying and Goldsmith can go either way. Fake names will typically be a natural thing. Baum, Berg (tree, mountain) these are often mixed with the colors, Rosenbaum, Grünbaum. It's not a caste thing they're just made up names. Also money related ones are common: silver, gold, diamond. Any name that ends in man is fake. Swartzman, Silverman. Klein (small) and Gross (large) are fake. Roth and Cohen are always kikes. Roth does not mean red, although they'll transliterate it that way Rothstein will become redstone. Roth was a slur, like Yankee or kike. Cohen is a false claim of biblical ancestry, like Israel which is another kike name.
