It was Rhaenys' mother who was a Baratheon, but yes, this is their belief. Incest was expected.

A note about Targaryen incest. They believe their blood is what enables them to control dragons. They marry within the family to not dilute that dragon controlling ability and they don't want to give this ability to other houses. That's why the girls usually marry in the family. The few exceptions are in Rhaenys' case (Baratheon) and Rhaenyra (Velaryon). Both those families are deeply tied to the Targaryens though.
