Still, my part-Cymric pride (grandma's maiden name was Phillips) is stirred by this development.
My grandfather was born in the shadow of Conway Castle. I am told one of his grandparents was from The Isle of Man. So I am 1/4th Welsh and 1/16th Manx. No tail though.
I saw an interesting report on the Aboriginal languages of Australia. It said that once there were 200 but now only about 20, but there is a new revival going on.
