No, but in the TV show Doran says "4 nieces" but the wiki for the TV show says they have 5 daughters. Hence the wiki must be wrong and the show is correct and in line with the books.

Yea, In the books. Sorry, I used this source http://gameofthrones.wikia.com/wiki/Ellaria_Sandwhich clearly states she has 5. I guess it's a mistake on that wiki. However, in the show Tyene calls Ellaria "Mother", but in the books she's the daughter of a septa.

Can someone answer this question: How many daughters does Elleria has with Oberyn? I thought it was 5, but Prince Doran said "you are a mother of four of my nieces". Mistake? I know it's probably not relevant in a grant scheme of things, but I just wanted to know.
