Intelligence and talent can be inherited. Values, sense of tradition, skills, and knowledge can be cultivated. A 200 year streak suggests, at least to me, that this particular family has done that well. If not, then they must be extraordinarily lucky. And, having mentioned Gretsch as an example, it's probably worth noting that Gretsch's slide into oblivion coincided with ownership leaving the family, only to be reversed when the family got it back.
