I am a big fan of the recent Jewish Tartan. Quite smart looking. In addition to Gordon, there are also Jews with the name Paton and I believe it's coincidence there as well.

The Welsh and Jews have some names in common like Lewis, Davies and Cowan, for the Jewish people it referes to Lewis = Levite, Davies, Davis, David = of David and Cowan = Cohen or High Priest descendant of Aaron, brother of Moses.

As far as coincidental names go, what about the MacIsaacs and MacJacobs, or the Hebrides (similar to Hebrew?), the Jacobite rebellion and the fact the the father of the Hebrews was named "Eber" as was the father of the Irish, hence "Hibernia"...

I'm not drawing any wild conclusions from these coincidences, although some less rigorous "academics" have....
