Pleasure mate. Glad it helped!
Her official position is daughter of the don, same as Gracie's (despite her not being ranked in the Family hierarchy), which commands respect from her Mother's position.
Her own Family rank is Capo (low-tier), but she is not as highly ranked in that regard as Caterina (mid-tier), the rollerskate capo.
So she is underneath Serpents, in the Family hierarchy, she's underneath Caterina, too.
But, because she's daughter of the donna, no-one is going to treat her with disrespect, as that would also be disrespectful towards Cordia.
Officially, a Serpent has the superiority of rank to order her around.
But, because of her being the daughter of the Donna, I expect that they would only pull rank to protect her.
