Scottish boy's name, two syllables, easy to spell, can't be shortened?

[WineSpider]

... i know this sounds really picky! Any ideas gratefully received!

Harris?

Iain, Ewan?

Tavish, Murdo, Callum, Errol, Duncan, Struan, Artair, Angus, Fraser?

Brodie, Cory, Struan, Jamie ?

Hamish or Callum.

Rory

Lachlan

Aaron

Hamish

Callan (Cal I know but it's a silly shortening)
Dougal
Duncan
Euan/Ewan
Evan
Gordon
Hamish
Ian
Logan
Magnus
Malcolm
Mungo
Murdoch
Murray
Neil/Neill
Padraig
Ranald

Archie

Dougray not traditional but like it from that actor.

Fraser

Hector

(but all names can be shortened, or lengthened and when at secondary age they may well be given a nickname by their friends that'll stick with them forever.......)

I love the name Fergus

Alec

As LizzieMacQueen says, any name can be shortened and many nicknames don't originate from given names.

In Scotland I have met:

Callum shortened to Cal
Lachlan shortened to Lachie
Dougal shortened to Dougie
Duncan shortened to Dochie
Malcolm shortened to Malkie
Fergus shortened to Fergie
Angus and Magnus shortened to Gus
Ranald/Ronald shortened to Ran/Ron
Padraig/Patrick shortened to Pat/Paddy

All these shortenings are perfectly normal.

Sorry, but Aaron is Biblical, not Scottish. The Scottish island is Arran.
Some Scottish people would pronounce 'Struan' as one syllable: 'Stroon' or occasionally 'Strowwhnn'

Gregor

Surely the name Gregor is going to be shortened to Greg, same with Fergus, that is likely to be no as Fergie.

Ivo

Douglas
Callum
Andrew
Rory
Robert

All names can be shorted or lengthened, especially if they are two syllabled. Even is parents don't want a nickname, children often acquire them.

Innes?

Hamish
Ramsey

Angus

Thank you for all the suggestions. Will chat through with DH tonight...!
