Hmmm...

You realise saffron kilts are Irish, right? Not sure why you post a list of your Scottish clans. Maybe that is why the saffron kilt is for sale?

FWIW, there are some Irish clans too, O'Callaghan is one of them. And yes, there is a Callaghan tartan, but a kilt in that tartan costs a lot more than a saffron one, which is why, amongst other things, I own the latter and not the former.

Authentic Irish kilts are either solid green or solid saffron. I own two green ones and saffron one, as well as a black one (?). I am wearing one of the solid green ones as I write this.

Then there are 7 or 8 general 'Irish' tartans of no particular authenticity. I own a couple of those as well. Then there are the tartans of the four kingdoms, and although I own none of those, Munster would be the appropriate one for me. Next come two entirely dissimilar sets of Irish county tartans, figments of the imaginations of two particular mills, and I confess I have the green Cork tartan.

The aforesaid Irish clan tartans are a bit pricey, on the whole more than their Scottish counterparts, although I aspire to one day own a Callaghan kilt, which is ironically woven only in Scotland. There are even a couple of London Irish tartans that have been designed to honour my native city, although AFAIK the only one actually available is the navy blue one, and available only from the same source and at the same price as Callaghan, i.e. from Dalgleish.
