Thank you for bringing that up.

I'd like to add another layer of symbolism to it.

Mac in Gaelic means "son."

Mac Isaac is the son of Isaac.

Isaac was Abraham's son, the younger one, who ended up with the blessing.

The other son was Esau, from whom the Edomites descend. The irresponsible, hotheaded one, who gave away his inheritance for a bowl of stew.

Some among the sons of Isaac, according to folkloric beliefs, became known as (I) 'Saac's sons.

Saxons.

As in Angles, Saxons, Jutes.

Sons of Isaac (not all called Saxons) wandered northward and westward.

Celts and Germanics.

So they say, anyway.

Back to the Gaels.

Some speakers of Gaelic, many many years ago, believed they were speaking Hebrew.

Scots believe they left Egypt and sojourned in Spain before ending up in Ireland, then Scotland.

Hence Hebrides. Iberia.

There's more, but that's enough for now.
