This is my family Tartan. It’s called the Shepherd Historic Family Tartan. I found it here: Tartan Finder v2.0
At first I was a little disapointed that it was so boring – the other Tartans had colors and more interesting patterns. Then I did some more surfing, I mean research: And found that the Shepherd Tartan is the ORIGINAL tartan. There’s some history on it at the Sheppard Family Assoication website. Interesting site with lots of links.
