* Immogen: This is the second most common variation. It's a more traditional spelling, sometimes preferred for its slightly more formal feel.
* Imogena: This spelling is less common than the other two, but still valid. It adds a touch of elegance to the name.
* Other variations: You might occasionally encounter spellings like "Imogenne" or "Immogene", though these are quite rare.
Ultimately, the "correct" spelling depends on personal preference and the specific context.
