I was adopted, and although my adopted parents are my 'Ma' and 'Pa' in every sense of the word (and I couldn't have wished for better) blood, I'm afraid, is thicker than water. My adopted (Father's) name has no clan connection whatsoever, whereas my bio Father was a true clansman (I put great store in facial recogntion and he has the classic 'clan look') and it is to his clan that I feel I belong, and feel a sense of real pride when I wear his tartan. Of course I don't wear this tartan when in the presence of my adopted Mother (my adopted Father sadly died years ago) so I have to have more than one kilt, one in the tartan of my true blood line and others in the tartans of my adopted Mother's lines. The only clan crest I ever wear though is that of my bio Father's clan.
