I'll check out the link. Sorry, but I hope I won't be looked down upon for not being of Highland descent. My mother's great grandfather, William Morehead came from Ulster between 1860 and 1870 (Census records) and settled in central New York (my home area). So far, I've tracked the Scottish spelling of the name (Muirhead) to Lanarkshire in the Lowlands. That makes it possible my forebears were involved in the Ulster Plantations of James VI; which begs the question: was he Scot, Irish, or Scots-Irish? I suspect there was eventual mixing between the Scots and the native Irish, although it was frowned upon in the early days of the Plantations, as the native Irish gaels were considered to be barbarians by the crown.
