Versions of the name Macrae appear in both Scotland and Ireland. DNA results have found them in SW Ireland, NW Ireland, and various areas of Scotland. The Scottish Highland Clan of Macraes first settled at Clunes, near Beauly, Inverness-shire, Scotland. In the 14th century a branch settled at Kintail in Ross-shire and became constables of Eilean Donan castle. In the ensuing years, members of this Highland clan, have scattered throughout the globe. This project hopes to enable clan members to learn more of their genetic heritage and to help them make connections between long-lost cousins.

Males are advised to test at either Y-DNA37 or Y-DNA111 to start. The Big Y-700 is the ultimate test for males.
