Isabel (Zaida) de Sevilla reina consorte de León - Justin you cannot state in the curator notation that: Her only proven child was a son named Sancho.

the theory is controversial.

A statement notation at the top of the page like such is Bias and as a curator you are placing a claim that leans towards Zaida De Sevilla not the mother of Sancha and Elivira.

-----------------------------------------------------
come on cousin; I posted many sources pointing to Zaida De Seviila as being the mother of Sancho, Sancha, and Elvira, as well as, posted a book source discussing this controversy leaning toward Zaida as the mother of all three.

I have seen no other references from you or anyone else supporting otherwise.

Your curator statement is biased.
