Socorro is a Spanish and Portuguese word name taken from a title of the Virgin Mary, "Mary of Perpetual Succour." Its religious meaning makes it somewhat old-fashioned and not among the Spanish names for girls widely used in the US.

Relief was a name used by the Puritans in reference to the relief of Christ. Leafy was the common nickname.

It sounds like a modern nature name, but Leafy was coined as a Puritan nickname for the girls' name Relief, which referred to the relief of Christ.
