Scottish Gaelic Names that Start With A

With many British names invading the Yankee name pool, the sophisticated Alistair could and should be part of the next wave. It debuted in the US Top 1000 in 2016. 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.

Alistair

In this country, more recognizable with the Alistair spelling. 

Alasdair

A surprisingly rare form of Arthur that rings more Scottish, and lends itself easily to Art as a nickname.

Artair

Angus is a traditional yet stylish choice in the UK, especially in Scotland. And it's a cool choice for US parents too, particularly those whose roots go back to Glasgow. The ancient Celtic form Oenghus has important historical overtones in Scotland, and the Gaelic form Aonghas is associated with two distinguished modern poets. In Irish folklore, Angus Og is a chieftain-lord who used his magical powers for the pleasure and prosperity of mankind--and in Irish myth, Aonghus was the god of love and youth.
 These days, Angus is even more popular in Australia than Scotland, possibly due to the fame of Scottish-born Australian musician Angus Young, lead guitarist and co-founder of the seminal rock band AC/DC.
 Other pop culture references: Angus was the first name of TV's McGyver and the young actor who plays the half man on Two and a Half Men is Angus T. Jones. Angus Wilson was a noted British novelist and short story writer.
