Very interesting. I was wondering why, when going through my father's things after he passed I found a Yarmulke. Then again my mother reminded me he had one to wear when attending his close friends Jewish celebrations.
But the above from you is interesting. Mayor Ed Koch used to assert every St Patrick's Day that Ireland was the refuge of the 'lost tribes' of Israel. I am sure he was just trying to score political points:)
There is much written on the Hebrew early history of Ireland, but they don’t all agree on which Israelite it was that settled there.
Whoever they were, they apparently had married a daughter of Pharaoh.

I find it very interesting too - Many will come tearing their garments and throwing dust in the air howling '!!British Israelism!!', but there are some truly significant things. Much of Irish, Scotch, Gaelic, and Brit lore was lost in the conquering of the Catholics and Nordics, but I spent a lot of time in early, early stuff, mostly bardic lore... There are some very intriguing pointers. Not only at Tara, but significantly too in Glastonbury.
