Slightly unusual boys names with great nicknames?

[user1471547428]

Hello, we have a son Raphael, known as Raffy or Rafe. We chose the name partly because we loved all the different nicknames.
If the next baby is a boy, I'm really having trouble thinking of any names.
I'd like something else a little unusual but doesn't have to be incredibly rare. And a good nickname (but not a very common one like Nick, Ben, Ali, Ed).
Names I might quite like are Rowan, Tristan, Leander, Griffin if that gives an idea of style.
Bonus points if it's Hebrew or Irish in origin.
Thank you!

I love Aldrin actually - never thought of that before - may add to our v short boys list!

TMNT - I wondered if it was that?! Haha I love it! Still working on Rafael with DH :-)

I love Kit as a nickname for Christopher (I think it is medieval in origin). We intended to use it as the nickname for ds1, but when he was born, it just didn't suit him.

OP I have 6 months left too ;) early nov. DS is called Jos, that's already been suggested. Not Josiah though. You've had lots of great suggestions which have been helpful for me too! Hate the naming process! Deffo finding out the sex just to narrow down the name options

I can think of many many amazing girls names but buys are very hard!

The other thing to remember is that nicknames don't have to be related to the actual name. Some of the best ones come up in completely different ways after the child is born. So if you love a name but can't think of a nickname, don't worry about that, just use it anyway.

I was going to suggest Jeremy.. nn Jem as I think thats fabulous.

Just one word of caution OP... you dont always get to choose the NN... he might just get called something age 4 at school which sticks for the rest of his life!

Casper - Cass

If you like Jem but not Jeremy, I know of a little James that goes by Jem. Also love the Christopher/Kit suggestion and Alexander/Xander suggestion!

Joah nn Joe/Joey?
