The Wilson tartan is not strictly speaking a clan tartan as there is no Wilson clan as such. As far as I am aware the surname simply means son of William or Son of Will, and the tartan was invented by Wilson's Mills of Bannockburn in the nineteenth century. Of course it is a beautiful tartan and as I have an Irish great-grandmother whose maiden name was Wilson and from whom my mother's middle name was Wilson, the Wilson tartan is one which I wear from time to time and I don't need to ask any clan chief or anyone else for permission to wear it.
