The grand mother of my father in law was named Clara and her Jewish name was Keila, which has 18 hits in David Rosen's list.Oded Freilich's suggested methodology is certainly not the way our ancestors looked at the question
My wife was named Claire after her great grandmother. However her Hebrew name is Sarah, being born on Shabbat "Chayei Sarah". In her youth though she looked for a Hebrew equivalent as Oded did. She found Bruria, which a special name from a Talmudic heroine.
