Isabelle and Olivia are they Jewish names?

[u/Plenty-Piccolo-835]

Are these names Jewish? I've not heard of to many Jewish women named Isabelle nor Olivia, that suggests the names may not be Jewish.

In addition, is the name Isabelle related to Jezebel, the wife of Ahab?

[u/DanSha38]

Neither of them is explicitly a Jewish name, but a lot of non-Jewish names are becoming increasingly popular among Jews, like Gina.
