The name Enola is a girl's name meaning "Alone". Enola and discussed in our forums with posts like "Olivia and Ian: A Brother - Sister Name Chain".
From the experts:
Let's be blunt about this: You should not name a child after the plane that dropped the atomic bomb on Hiroshima, Enola Gay. Especially since that name was first coined in a poem from a few decades before the bombing; it's not one of those names that has a ton of great connections and one bad one. It just has the bad one.
