Suppose I want to speak of the daughter of a man with a heritable cognonmen. Let us take Marcus Tullius Cicero as an example. If I want to clarify that the Tullia I am speaking of is his daughter (or at least, a woman of his more immediate agnatic family), do I call her Tullia Cicero, Tullia Ciceronis, or Tullia Ciceronum?
Also, if the practice changed over time, I'd be interested to know that as well. My interest is not limited to the 1st century BC (but is focused on roughly 200 BC - 400 AD).
