****But "roughly" does not work here. They have to know exactly when she lived in order to find her. And I highly doubt the years of her birth and death are more esoteric than the name of her dynasty. Is the name of Elizabeth I of England's dynasty a more esoteric piece of information than her years of birth and death? The guideline I cite is quite clear: "Years of birth and death are not normally used as disambiguators (readers are more likely to be seeking this information than to already know it)."
