As we work to remove questionable lines from King David of Israel to the present day, one line we need to think about closely is the one that goes through Paloma ha-Leví Benveniste. The line is not accepted by the majority of modern experts, but there is a chance that it -- or something like it -- might be correct. Also, it has some very zealous defenders both on and off Geni because it without it, there is no good, verified line from David to anyone living today.
Here's the short version. Alonso Enríquez de Castilla, 1er. Almirante Mayor de Castilla, Señor de Medina de Rio Seco, Admiral of Castile, is said to have had an unnamed Jewish (or maybe Moorish) mother. Alfonso's father was Fadrique Alfonso de Haro, an illegitimate son of Alfonso XI of Castile.
Some experts think Alfonso's Jewish mother might have been propaganda. Others think it could be true. It would be consistent with the later generations of Spaniards who wanted to suppress any evidence of Jewish ancestry.
A later chronicler names Alfonso's mother as Paloma ("Dove"). Still later, a romance said Alfonso was really the illegitimate son of Queen Blanche de Bourbon, but he was raised by a Jewish girl named Paloma.
There is no direct, contemporary evidence about Alfonso's mother or her ancestry. In modern times the theory developed that Paloma, might have been the same person as Yonati, who is said to have been a daughter of Gedalia Shlomo ibn ben Shlomo ibn Yaḥyā haZaken, who was head of the Jewish community in Castile.
The main argument in favor of this identification is that the only Jewish woman prominent enough to be a mistress of an illegitimate son of the king would have been a daughter of Gedalia.
I suggest we disentangle this identification (pending further research). Have one profile for Yonati, supposed daughter of Gedalia. And another profile for Paloma, mistress of Fadrique Alfonso and mother of Alfonso Enríquez.
Here are two Wikipedia articles and one Wikimedia article that give a better sense of the problem:
