My DH is Dutch so we are definitely open to 'Dutch' names but any boys' names that are uncommon but not unusual.
We need them to go with the surname Kuiper (Kai-per) and we haven't decided on middle names (or even if we're having them!) yet - but if we do they will likely be the first names we didn't choose.
Some names we like so far are Sem, Reece/Reis, Luca/Lucas/Lukas, Levi, Ellis, and Jenson.
Any suggestions would be appreciated.
