George Abernethy de Barries' sons (if one buys the assumption that they were indeed brothers) both born in Scotland are said to have come as deported prisoners or indentured servants to the "colonies" ca. 1652 after the defeat of the Scots at Culloden. Robert Abernethy settled in NC & William Abernethy settled in Connecticut. Both sired sons who are the ancestors of most if not all the US Abernathys. The significance of the a/e spellings are also matters of some dispute, although my assumption is that these old geezers were just terriblle spellers. See some of the postings by John Abernathy Smith in this forum as well as Brian Abernathy's web page (if is is still available) "Descendants of George Abernethy de Barrie.
