Is there a term for children whose parents' marriage ends with nullity?

In its discussion of marriage, the *Catechism of the Catholic Church* (*CCC*) states, "The Church holds the exchange of consent between the spouses to be the indispensable element"(*CCC* __1626__) that seals the covenant of matrimony. "If this freedom is lacking, the marriage is invalid." (*CCC* __1628__) The *CCC* goes on to say, "For this reason (or for other reasons that render the marriage null and void), the Church ... can declare a nullity of marriage, i.e., that the marriage never existed." (*CCC* __1629__) In consideration of this, it lends to question what the nature of the sexual relations were if the marriage never existed. However, that's an aside; it's the children of such a union I'm asking about. Presumptively, these are children baptized in the Church with godparents. __Is there a term for children born from what was thought to be a valid Catholic marriage whose parents then go through legal divorce and the Church delclares the marriage null__? Please no derogatory answers, but if there's something "you've heard somewhere," feel free to add as a comment with some context.
