hi i'm a wilkinson from devon. i am trying to find my family crest and tartan. can anyone help me?

The only thing I could find is that you are affiliated with the MacDonald clan but I don't think there is even a sept with the Wilkinson name. So I imagine that you would use a MacDonald clan one. There is an English Wilkinson crest that I did find though. you can go to electricscotland.com and find info.
