Alice de Courtenay - parents of William Taillefer

Alice de Courtenay was married twice first husband was Guillaume 1 Comte de Joigny second husband was Aymer Taillefer d Angouleme he is the father of William Taillefer @ Alice de Courtenay

Sorry, Judy - should have been more specific. The About section states that there was no issue from her 1st marriage & that she had only 1 child, Isabella, by her 2nd marriage to Aymer Taillefer. But, 3 children are listed in her profile, so there is a conflict here.
Thanks!

Other sources say she only had one child, that being Isabel/Isabella.
