Onni

It is certainly a stroke of luck that you stumbled upon this distinctive option! Onni is a boy's name of Finnish origin. If you're intending to remind baby of the most important priorities in life with just their name, then this one meaning "happiness" and "luck" will give the well wishes you've been looking for. Onni is one of the most popular masculine names in Finland, but is relatively unknown in other places of the world. As such, it would work well to keep baby connected to their Nordic heritage, while also helping them stand out on any playground.
