Most of the names cited as "out of favor" still seem to be reasonably common in my area, but then we are a century or two behind the rest of the world.

A very common name ca. 1940 for girls was Enola, but that lasted only a few (war) years. It might be popular again someday(?).

For unusual(?), it would be difficult to beat my Great Grandmother Berthsheba Elianor. I doubt that either of those shows up very often, and I doubt if either of them will pop up on newborns anytime soon.

The family does include one Geneva and one Radine, neither of which - so far as I know - was ever very common.
