About us

The ultimate objective of this project is to help people learn more about their Conner / Connor / O'Connor ancestry

The typical questions that DNA Projects like this one can answer are:


  1. To which Conner / Connor / O'Connor individuals am I most closely related? Will this help me push back my own Connor genealogy a couple of generations?
  2. From where does my own particular Conner / Connor / O'Connor branch originate?
  3. Is it possible to link my Conner / Connor / O'Connor branch to the ancient genealogies as described in the Ancient Irish Annals?
  4. What can DNA tell us about the origins and evolution of the surname Conner / Connor / O'Connor and its different variants? How are they related to each other (if at all)?
  5. What does the larger Family Tree of the Conner / Connor / O'Connor surname look like going back to the origins of the surname? Can we define it based on the mutations we find in the DNA?

Therefore, the Goals of this Project can be summarized as follows:

  1. To identify distinct genetic groups of people carrying the Conner / Connor / O'Connor surname (or one of its variants)
  2. To analyze each genetic group and assess where did it come from, how old it is, and if there is any connection to a pre-surname "clan"?
  3. To communicate the conclusions of the analysis for each genetic group
  4. To help focus project members on specific directions for their own ongoing genealogical research

In order to achieve these goals, there are several things that members can do to help themselves and each other.

1) Fill in your MDKA information (Most Distant Known Ancestor) for both your maternal line and (especially) your paternal line. Surname spelling & birth location are the most important details. Simply click on your name in the top right of your home page after logging in - click on Account Settings - Genealogy - Most Distant Ancestors ... I have posted instructions on how to do this on the following link.


2) Post your Conner / O'Connor Pedigree to the Activity Feed. This will potentially help other people to connect with you. It would be best if you could provide it in the following format:


  1. James O'Connor b c1835 Shallee, Co. Tipperary, d 12 Nov 1879 Longstone, Co. Tipperary, m 13 Apr 1860 Maria FARRELL, Silvermines, Co. Tipperary
  2. xxx
  3. xxx
  4. xxx … but not including dates for a) births <100 years ago, b) marriages <75 years ago, or c) deaths <50 years ago
  5. the DNA kit owner (you can use initials, the last 4 digits of your kit number, or simply say "kit owner"). Be sure to protect other people's privacy. You can also include your email address if you wish to be contacted by fellow researchers - I recommend to take the @ sign out and replace it with AT (for added security). And also please include a link to any online family tree that you have.


3) Add your Ancestral Surnames (click on your name in the top right of your home page after logging in - click on Account Settings - Genealogy - Surnames). I suggest to put SURNAMES in capital letters and Locations in normal text.



Adding these 3 essential pieces of information to your online presence will maximise the chances of finding long lost cousins and breaking through your Brick Walls.
