- Dr. Maurice Gleeson is by profession a psychiatrist and pharmaceutical physician. He is also an avid genealogist who has developed a strong interest in using DNA as an extra tool to assist family history research. He first used genetic testing in 2008 and by so doing traced his Spierin family connections back to the 1600s in Limerick, thus breaking through the Brick Wall that most people hit in their Irish research around about 1800. He has also set up the iCARA project to help people with Irish surnames in the Caribbean find their Irish ancestry, and is co-administrator of the Ireland mitochondrial DNA project .
Thursday 20th Feb, 11.15 - Autosomal DNA -- a step-by-step approach to analysing your atDNA matches
This talk will focus almost exclusively on autosomal DNA and how to use it to find long lost cousins. Maurice will explain a step-by-step approach to assessing your "matches" on the autosomal DNA test and how to narrow down the number of potential candidates for the common ancestor that you share with each match. In this regard, the adoption community in the US have developed some amazing tools to help with this process and Maurice will be looking at how the methodology can be applied to ordinary family tree research (with a particular focus on its potential usefulness from an Irish perspective).

I recently got my dad tested and the results now make much more sense and I can rule people out! I am inspired to test more people in my family - it is very helpful to break through "brick walls".
Enjoyed the video, and thought the audio was fine. This is very inspiring, enough to actually get me to have my parents DNA tested on Ancestry. Thanks for posting
Totally fascinating work being done by Mr. Donald Yates
This is really helpful! So glad I found it. Very clearly explained.
very good presentation no problems with the audio but I'll have to replay and take notes....thanks
There is nothing wrong with the audio on this video you need to get your hearing check very good video...
Ancestry DNA testing is available in Australia
I have taken several DNA test from different companies. I was under the impression that paternal DNA can not be determined via a female. However, I see that Ancestry DNA was able to trace my paternal DNA via the sample I submitted. And I am a female, genetically, phenotypically and physically.
Reina, only a male can take a Y test, but anyone can take the autosomal test (and I'm assuming that's what you took). The Y test gives the results for your father's father's father's etc. The autosomal test checks all branches of your family tree within the last several generations.
Did he say that the average man is less of a person than a woman? I am not sure, the audio is so bad.
It was a joke.. the Y chromosome is about a 3rd the length of the X chromosome.. he said "scientifically it's proven men are less of a person than women"
There is endogamy among the Acadians.
All my matches with Acadian ancestry are descended from cousin marriage partners.
+Raymond Nolan Scott I too have Acadian Ancestry - per chance ir it from a Alexander Brotherton (Brotherstain)
Mine comes from my 4th Great Grandmother Anastasia Bourgeois of Plattenville, Assumption Parish, Louisiana who married my 4th Great Grandfather Benjamin Cross of Gates County, North Carolina. They were the paternal grandparents of my paternal grandmother's maternal grandfather.
If a female has a son does he get any of the dna from his maternal grandparents?
I am so lost with DNA ... what is the site that you can download the tools please i have my DNA with FTDNA but my matrix feature doesn't work
I think you are looking for gedmatch.com
A common ancestor out of 8 billion people on earth, is as irrelevant as, the inherited % of one of the 1,048,576 contributes to their own DNA after 20 generations.
The reality is, 2 ^23 making 8 million possible combinations makes one is a uniquely distinct individual, where no one is the same or has ever been the same or will ever be the same.
What do I think? I think you should take this POS down, buy a decent microphone for well under $100 and redo the audio. This is especially easy because all you have here is a podcast with slides. It is very difficult to understand the audio. You are going to be offscreen so you can use a inexpensive wired microphone and make the sound 10 times better. As it is, you have gone to a commencement of work to produce something that is completely unacceptable.
***** Well, I have had my DNA tested thus making a market for this kind of information.I have made the results public on SNPpedia. It probably wasn't necessary to use the POS comment. If you want to complain about something, you should complain about my redundancy as other people have already noted the poor audio. I suppose poor audio is better than none.

I could hear it fine, maybe you should clean your ears out or perhaps show us your videos that you have taken the time to create and share?
