You could consider checking an encyclopaedia on the matter. I checked the English Wikipedia page on the matter for you. On the literal 2nd paragraph, they talk about second-generation immigrants. My point is that you seem too stubborn to accept any use of the word apart from that of a dictionary. But I think we can all agree that language contains more than can fit in a dictionary. Therefore, you should acknowledge uses outside those found in a dictionary, like the use described in most encyclopaedias - I must image - on the matter. Also I find your comment rude, which is just double annoying when you furthermore seem misinformed on the matter.
