Few have done alone what Robert Listet Macneil did. The Clan Menzies have, but it took the whole clan, plus government grants, as in Macneils case. The interesting thing is how in Hebrides, Clans that claimed to be sharks proved to be Vikings and clans that claimed to be Vikings proved to be Gaels. The Macneils always claimed to be descendants of Niall Noigallach (Neill of the Nine Hostages), perhaps in retrospect an obvious claim given their surname, but Vikings liked the name too, as MacNeil DNA shows.
