David has some good advice. If your intent is to wear a tartan connected with your family roots, you should be aware that these Welsh family name tartans are recent inventions and that the Welsh did not have a tradition of wearing family tartans.

As modern commercial designs, these tartans are all owned and copyrighted by the Welsh Tartan Centre in Cardiff, Wales, which is the company responsible for creating them. This means that you can only obtain those tartans from the Welsh Tartan Centre or those retailers carrying their products.

As all the tartan will be coming from the same source, you are not likely to find much variance in the price or product availability.
