Updated 14 September 2024. The Big Y 700 is our test of choice for males. To help find family connections for the RUDDENKLAUs 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. If your surname is RUDDENKLAU or suspect your earlier name was similar (eg. RÖDENKLAU), then please join this project. It matters not whether you are male or female nor what test you have taken – DNA will have the final “say”.
