Alistair

With many British names invading the Yankee name pool, the sophisticated Alistair could and should be part of the next wave. You have a triple choice with this name--the British spell it Alistair or Alastair, while the Scots prefer Alasdair--but they're all suave Gaelic versions of Alexander. Adopted by the lowland Scots by the seventeenth century, the name didn't become popular outside Scotland and Ireland until the twentieth century.

Both Andrew Lloyd-Weber and Rod Stewart chose the Alastair spelling for their sons' names.
