Till recently the family accepted the fact that we were Irish, then I started digging; one good place to start is surname search on ElectricScotland.com. For years and years, the English used the Scots to "control" the Irish, seems the surname we thought was Irish was really Scottish.

Keep digging you may be surprised what you find.

Of course the Irish Sea is such a wide expanse that no one could have possibly sailed it before say 3000 BCE, or could they?
