Need a traditional boy name that is NOT in the "top ten".

Love traditional names, but because of the timelessness of them, you hear them over and over... So sick of William, Johnathan, James, Michael, etc. The trend of old-time names making a resurgence is something we want to avoid (like Theodore or Henry)

Need something classic, but a bit unique and cool. Preferably origin from the British Isles.

Any thoughts? Open to all suggestions!
