Updated 14 September 2024 The Big Y 700 is our test of choice for males. To help find family connections for the McCALLs of all spelling and variations. By joining the group you agree to provide the project with 3 things. 1) The surname of the person being tested. 2) The name, date and place of birth of the oldest researched male ancestor of your male patrilineal line and the oldest researched female ancestor of your matrilineal line. 3) Permission to publish the DNA results and the names, dates and places of birth of the oldest known patrilineal or matrilineal ancestor. This is a surname Project for those with the McCall (or variant) surname along with those who know that they are McCall but for some past reason, a name change occurred. Men who test their Y chromosome, need to be at least at Y111 to get the benefit, but preferably the Big Y 700.
