Scottish sibling name for Logan?

[Popskipiekin]

We are expecting our second boy and already have a Logan. We would love another Scottish name. Our surname is two syllables, ending -ie. So far DH and I like Finlay - he would be known as Finn - and are arguing about Cameron which I don't like as it makes me think of David Cameron but I know that's silly .
What do you think about Dougal (spelt any number of ways)? and any other ideas? A very good friend's boy is Douglas so I feel I can't use it although I do like it.
Thank you!

Ok I like all this positive affirmation of Dougal
Lachlan is great - those suggesting it do you not feel it's too similar to Logan? Maybe I'm too sensitive about similarities.
DH quite likes Harrison - so Harris/Harry could be shorter versions or nn.
Duncan definitely going on the list. Thanks for all the input! Have decided not to discuss with family before announcing (total disaster doing that first time round though they all claim Logan is the bee's knees now ) so it's so helpful to have all these ideas.

I like Lachlan but ruled it out due to potential mispronouncing. The a should sound like an o ie 'locklan' but I've heard a lot of 'lacklans' too.....just something to consider!!

I love the name caleb :) It s Scottish in origin isn't it?

I have a logan and there was a harris and an alasdair at the water babies group we went to

Lewis is very popular at, so Harris is a great alternative. Finley is really nice and not very popular here, but may be where you are?

Rory, Douglas, Alastair

I love Innis.

I think 'Innis' would be 'Innes' for a boy.

dotdotdot Glad DD2 wasn't a boy then! That would have been embarrassing...

Fergus. Best name ever.

Lovely names! Thanks all. we're building up a fabulous shortlist. I had no idea Caleb was Scottish - only knew of the Biblical connection.
Seashell we are in London - "expat" Scots - and I don't know any Finley/Finlay/Finns but we don't mix with many children yet.
I'll let you know the final choice when DS2 arrives but don't hold your breath as we're a few months off that point...

Caleb is currently quite popular in Scotland (129 babies with that name in 2015), but it is Hebrew (Old Testament).

Like other Biblical names, it became more widely used in Scotland after the Protestant Reformation. So it's been around in Scotland for 400 years and more, but - unlike Dougal and Duncan and many of the other names mentioned on this thread - it is not Scottish in origin.

I like siblings having names with a common theme. You could have the Scottish connection plus the same first letter with, for example, Lewis.

Lewis James has a great sound to it.

Aibne

I know the most gorgeous brothers called Logan and Cormac.

More Celtic than pure Scottish, but they are known as Logie and Mac.

Willowfrost - I am not saying that your name Aibne doesn't exist, but, please, where are you getting it from? I've tried googling it, and all that comes up are some baby name sites, and we all know how unreliable most of them are, plus some really nasty stuff from Urban Dictionary.

The baby name sites say that 'Aibne' means 'River'. But 'Abhainn' is the usual Gaelic spelling for river. ...And 'bn' is a very unusal consonant pairing for Gaelic.

Lachlan?
