Jalmari

For some reason, it kinda reminds me of calamari.

This is an old-fashioned name, and it has a comical sound to it, which is why people here in Finland would laugh at you and pity your son if you named him Jalmari.

Jalmari is a nice unique name. It is uncommon. It is also similar to Yolmer which is nice as well. I had a relative with that name. But it's not a name I would give my on child.
