Wikipedia has a pretty impressive list of unisex names available for your perusal. For inclusion, each name must fit at least one of these criteria:
- have originated as a unisex name (e.g., Abijah).
- have multiple origins as both a masculine and feminine name (e.g., Alva).
- have been used significantly at some point in the past or present as a name for both males and females (e.g., Tristan).
- be used as a nickname for both masculine and feminine names (e.g., Chris).
- be otherwise significant in a historical context as a unisex name (e.g., Zooey).
Many of the names on the list, surprisingly, don’t strike me as unisex. But maybe my worldview is small. That’s been proven to be the case more than once in the past.
