Comments for the name Teunis

Dutch pronunciation is TOY-nis (the EU is a sound between OY and AY). [noted -ed]

This is my dad's name, he goes by Teus.

Teunis was my great-grandfather's middle name and I'd love to use it, but I don't really think it's practical in a completely English-speaking context. He would probably agree, since he Anglicized it to the unrelated Dennis before he passed it on to his own son.
