The purpose of the MacRae/McRae Surname project is:

•To identify others who are related and to bring together related people who may have scattered to many countries of the world.
•To assist MacRaes of any spelling and other historically related groups to find cousins; determine family location and movement; and, when possible, determine clan branch or cadet line.
•To help people prove or disprove theories regarding their family history or ancestry with an additional resource.
•To investigate through DNA the deep ancestral roots of the clan.
•To share with other DNA project managers information on Scottish and Irish genealogy.
•To determine if Clan MacRae has multiple progenitors of different ancestry, such as Celtic and Scandinavian.
