Did Cleopatra marry her two brothers?

However, we do know that she married her two half-brothers, as was the way of the Ptolemy empire. She married Ptolemy XIII (who was later drowned while running from Caesar's troops)and Ptolemy XIV, then eleven (11) years old (who was later poisoned) Both of Cleopatra's younger half brothers were born to her father's second wife. Cleopatra's first meeting with Caesar was in order to get his help - to make her brother reconcile, with her, and allow her back into Egypt from her exile.

This event was the famous Cleo in a rug ploy. After this meeting Caesar was so taken with this nubile young woman of twenty-one that he had her brother drowned in the Nile River, while he was in his battle armor.
