Yet another tartan question -- I'm just full of 'em -- although some say it

I looked at the tartan registry and found it to be a great tool. But I was wondering if anyone knew of any tartan specifically associated with the Roman Catholic church, or any organisations such as the Knights of Columbus -- or which I am a member.

I haven't seen anything in any stuff from the Knights. I would imagine that it is possible that the Irish and UK counterparts, the Knights of Saint Columbanus or Knights of St Columba, have a tartan, but I probably wouldn't be entitled to wear it.

Just curious
