DC6 has arrived but is nameless - please help us!

[UsedToBeAPunk]

The newest addition to our brood arrived 8 days ago but we have no idea what to call him! Our other 5 are Jasper, Matilda (Mattie), Arlo, Devlin and Stephanie. As there is a very large age gab between oldest and new arrival (oldest is 16) our taste has changed and we don't really have a particular favourite type of name IYSWIM? So any suggestions on what we should call our little boy?

My favourite uncommonly used boys names include:

Vincent
Rollo
Iestyn
Andreas

Of the more normal ones how about:
Mark
Nathan
Ben/Benjamin
Rhys

Thanks for all of your feedback! It was a tough decision and our final three were Miles, Roman and Reuben and in the end we went with Roman :)

Lovely!

ahh Roman is a fab name!
