It's a shame it's not true, because it's a nice idea. I thought it was until we studied the Saxons at school and I realised it couldn't be.

I can't think of a place or area called Absin, and I didn't find anything on Google - just a lot of references to absinthe. I wonder if it could be an abbreviation, although for what I don't know. It may be a place that no longer exists. A lot of villages disappeared after the industrial revolution because the inhabitants moved into towns. One more thought, as England is written in Dutch, maybe the place name has been translated too, in other words it could be the Dutch version of the English name - the Jarleston you mentioned is actually spelt with a 'y'.

It's interesting to see how the name of the country has changed though, nowadays England is called Engeland in Dutch.

This is a real mystery, I'm dying to know where Absin was.
