Why would you need a piece of paper to qualify your heritage? Surely its enough to know that you have Celtic heritage? When someone asks you why you are wearing a Saffron coloured kilt are you going to rummage in your sporran and produce a certificate of a long lost ancestor or are you just going to say that you are descended from a noble celtic kinsman. My father was born in Wales and I know that I could wear a Welsh Cilt if I wanted too, The feeling or for the want of a better word "hiraeth" is imbedded within my spirit, I know that I can wear the Cilt or the Kilt (on my mothers side) and that is enough for me.
