ASOIAF:Who is the heir to Dorne?

In the books, the heir to Dorne is and always was Arianne Martell.

However, Doran had other plans for her; originally his plan was for her to marry Viserys Targaryen(Daenerys' brother.) In which case, she would become the queen of the Seven Kingdoms, and the inheritance would fall to Quentyn Martell. However, Viserys died(as we know) and that put an end to that plan.

The new plan seems to be to try to betroth Arianne to Aegon VI Targaryen, whose cause Dorne would join to depose the Baratheon dynasty.

If that were to happen, the heir to Dorne would then become Trystane Martell, a ten year old boy.

Of course, the show is different. Arrianne and Quentyn didn't exist in the show, and Trystane was a teenaged heir to Dorne all along.

There is not enough information on the Dornish family tree extende family to say who would be the heir if such a situation happened in the book. Presumably there are cousins or second cousins who would be next in line if Arianne and Trystane were both killed.

It's unclear if it really even matters in Show! Dorne. My impression from the lack of reaction from the guards at their leige lords murder, was that there was support for the Sand Snakes' coup in Dorne.
