As someone who is adopted, I can tell you how difficult and confusing it can be to take pride in a Scottish heritage you may know very little or nothing about. Personally, all I know is that Scottish ancestry is part of my blood, but nothing else.

The good news is that adoptees have a wonderful freedom to pick the tartan they prefer. On the conservative side, traditionalists would recommend that you try and learn your biological history and go with that clan. Modernists have said that you can (and maybe should) adopt the clan of your adoptive parents if they have Scottish history. No doubt they would be honored! Or as a final choice, you can pick whichever tartan you like.

Whether you choose by color or feel a particular bond with a particular clan, the choice is yours. There are universal tartans (like Scottish National or Blackwatch) that you can choose as well. The important thing is to find a tartan that will mean something to you for the rest of your life. Visit a local kiltmaker or view the many tartan websites on the 'net. Above all - make it mean something.
