Getting the Most out of your DNA Test

No matter which test you have taken, there are a few essential actions you should take to get the most out of your DNA test. You may not be able to do all of them all at once, so come back to this page often and check it out again to see if there is anything else you could be doing to maximise the value you get from your DNA test.

You may wish to share the link to this page with any potential recruits so that they can see what they will get if they test.

Make yourself visible to your cousins

1) Send us your Gleason/Gleeson Ancestral Line (from you up to your Gleason MDKA). This will go up on our Patriarchs & Matriarchs Page on the blog or the Patriarchs Page on the WFN website (it depends on what kind of DNA test you have done). This will potentially help other people to connect with you. It would help if you could provide it in the following format:
1) James GLEESON b c1835 Shallee, Co. Tipperary, d 12 Nov 1879 Longstone, Co. Tipperary, m 13 Apr 1860 Maria COYLE, Silvermines, Co. Tipperary
2) Morty GLEESON ...
3) John GLEESON ...
4) Abigail GLEESON … but not including dates for a) births <100 years ago, b) marriages <75 years ago, or c) deaths <50 years ago
Researcher: (insert your initials here)
Your email address
DNA Kits: (insert your DNA kit numbers)

2) Use your kit number and password to Log in to your personal webpage and explore it. There are a lot of bits & pieces of information you can include on your personal webpage that will optimise your chances of successful collaboration with your DNA matches. And knowing what your DNA results can tell you will help you get the most out of them.

3) You should add your MDKA information (Most Distant Known Ancestor) including dates & locations for both birth and death. The format we recommend is the same as the one above, but you may have to abbreviate it as only a certain number of letters are allowed in this field. Location of birth is the most important piece of information. Here is an example:
James GLEESON b1835 Shallee, Tipp, d1879 Longstone, Tipp
To add this information, simply click on your name in the top right of your homepage - Account Settings - Genealogy - Most Distant Ancestors ... I have posted instructions on how to do this on the following link ...

4) Fill out your MDKA Profile. In essence, this is your Brick Wall. And the more information you can give about it, the better the chance of breaking through it. There are lots of clues and circumstantial evidence from documentary data that may help you identify a possible connection with other members of the group.  This applies to all project members but is most relevant to members with Irish ancestry given that the records tend to peter out about 1800. Check out the MDKA Profile page for instructions on how to complete the profile for your own MDKA. You can also view an example of it here.

5) Add your Ancestral Surnames (click on your name in the top right - Account Settings - Genealogy - Surnames). I suggest to put SURNAMES in capital letters and Locations in normal text, as this makes the surnames "jump out" and easier for the reader to scan through.

6) Upload your Family Tree as a GEDCOM file so that you have a version of your family tree on your FTDNA webpages.   This is particularly important if you have done a Family Finder test (autosomal DNA). You can also add your Family Tree manually if it is easier for you. And if you have a Family Tree online, leave a link to it in the About Me section of your Personal Profile. Click here for specific instructions on uploading a Gedcom file -

7) Optimise your Privacy settings so that your potential cousins can see your results:
  • Hover over your Name in the top right
  • Click on Account Settings, then the Privacy & Sharing tab at the end of the menu bar above
  • Then scroll down to last section entitled Project Sharing
  • under Group Project Profile, simply tick the box on the right beside “Opt in to sharing” …
  • Then click the orange Save button (bottom left).

Check out Project-related Resources

There are a lot of resources that are particularly relevant to the Gleason/Gleeson DNA Project and you should check out and use these as you feel appropriate.

8) Join the Gleeson Genealogy Forum on Facebook if you haven’t already. It is a great place for sharing information and keeping in touch with recent developments.

9) Check out the various pages and the previous posts on this website (the Gleason / Gleeson DNA Project blog). It has a lot of useful information that will help you understand your results.

10) Each Y-DNA-tested member of the project gets a Privatised Personalised Report which includes an interpretation of their results, how they relate to others within the project, and next steps for that particular individual. These reports are published here on this blog for the benefit of everyone - prospective new recruits can thus see what they will get and everybody benefits from the general educational aspect of these reports.

11) Join the relevant Haplogroup projects
Your results will reveal your haplogroup (your branch of the human Y-DNA tree and/or human mtDNA tree). Once your results arrive, make sure you join all the relevant projects as these will assist us in the further analysis of your data and in particular your deep ancestry (where in the world your particular ancestors originated several thousand years ago). The projects are run by volunteer project administrators and they are a rich source for advice, guidance, and support. Frequently there is an associated mailing list or Facebook group you can join to keep abreast of up-to-date developments (this is a fast-moving field).

Relevant Y-DNA haplogroup projects for each of the Gleason Lineages identified thus far include the following:

Check out General Resources

There is a lot of information out there about genetic genealogy in general and it can be a bit confusing knowing where to find it. Below is a selection of our "best bits".

13) FTDNA have a lot of useful information in their Learning Centre. Be sure to check out the FAQs (Frequently Asked Questions).

14) The ISOGG wiki is a great place to start looking for general information about any topic related to genetic genealogy, including your particular type of test.

15) Read Kelly Wheaton's beginners’ guide to genetic genealogy:

16) Download and read the e-book from the resources tab on your myFTDNA homepage.

17) There are a variety of different YouTube videos on genetic genealogy which have been prepared by ISOGG members and Project Administrators.

18) Sign up to the relevant genetic genealogy mailing lists, forums and Facebook groups. These can be great sources of help if you have a specific question. See the list here:
We particularly recommend:

19) Read blogs written by experienced genetic genealogists. See this list of genetic genealogy blogs:

20) Read the relevant articles about your specific DNA-test ...

  1. I love reading and I am always searching for informative information like this. I am very happy to your post about on. Great information, I would like to say your post is very informative.
    ssri genetic testing

  2. I've been searching for my great grandfathers parents name i know they where born in England and they came to ontario cause my great grand father Moise or Moses Gleeson was born there been looking for 2 years but found nothing,

  3. I am in the US. I have traceability that my grandfather Gleeson came from the North Tipperary Gleeson's. Problem is my dad was adopted. Still I'm interested in knowing more about this linage but don't think my DNA will help. -Robert Gleeson
