Another Jonna is Jonna Mendez, a veteran CIA field agent who was also Chief of Disguise at one point. Her husband was Tony Mendez (of Argo fame). Her videos for Wired and other channels are fascinating!I think of this name as: ✔ Feminine without being frilly. The -a ending gives it a flair without being sickeningly sweet or overly cutesy. ✔ Strong and confident. Jonna sounds like someone who knows what she wants and works hard for it. ✔ A nice tribute to a dad, grandfather, etc with the name John/Jon ✔ Fresh and underused. ✔ A good name for all ages, from baby to older adult.
