Surnames are a relatively recent innovation in human history (they came into wide use when the sovereigns needed to distinguish people of the same given name from one another for tax collection purposes).
In Jewish tradition, a person is known as the son or daughter of their mother while alive, and of their father after death (or when being called to the Torah). On gravestones, few have the surnames (at least in Hebrew) of the father (though in Israel the stones with surnames have proliferated over the past century).
