Well I love it! So I used it! (Outs self completely!
)
My Griffin is 16 now and we've only ever had compliments about it, it goes perfectly with our surname, it's easy to spell, obvious pronunciation, interesting but not 'out there'.
I thought we'd abbreviate to Finn, but he's mostly Griffin, Griff or Griffy (the last only at home!)
After picking it I subsequently discovered it was the name of the local brewery and the ground of our local football team! Still love it. If you've worked out you know me PM if you want. 
Best name ever! So there!
