Working with DNA matches

I did my spitting in the tube way back in 2013. At that time ‘23 and me’ was my choice for my DNA testing company. I had read all of Bryan Sykes books. Starting with “The Seven Daughters of Eve” And was inspired to take my genealogy to the next level. At that time I had been doing Family History for 27 years and had reached the point where I was looking for means of addressing my ‘brick walls’. After five years there are so many more companies jumping into the DNA pool. The most prominent ones include, 23 and Me, Ancestry, Family Tree DNA, My Heritage, and National Geographic. AncestryDNA touts they have tested a total 9 million. while 23 and Me in has tested 5 million with My Heritage and Family Tree DNA following in the numbers.¹ It is Big Business!

What do these numbers mean for the genealogist that is trying to solve brick walls through genetic DNA.

As more individuals test the chances of solving family questions increases.

Questions to ask:

  • Where in the world will I find the answers to my questions?
  • Are large numbers testing in that region?
  • How many of those 15 million + individuals that took a DNA test did so for reasons other then genealogy discoveries?

What percentage just did it to find out if they really were of a certain ethnic group like Native American, Italian, or say Irish.  That means a percentage of your matches may not have any information such as trees, family names and or family locations attached, or when attempting to contact them for more information they never respond or their response is less then helpful.

The large companies are diligently working to grow their numbers. You see their ads everywhere, especially around the holidays. This is good for business and may increase their numbers to improve their algorithms. But without just a few hints from those signing up, of how they may be related to you (family names and/or locations), just being identified as ‘third to fifth cousin’ does next to nothing to help you solve those questions in your family tree.

My Plan

  • Identify matches that are related to my maternal 2x great grandfather
  • identify their ancestors.
  • Identify location in 1846 and prior.
  • Identify the connection.

Genetically I have three male cousins, a brother, plus two sisters. Those are my closest, oldest known living relatives. Not much there for solving my ‘brick walls’.

All my cousins are on my mothers side of the family, luckily that is where my questions are. One cousin on my mothers line tested for us with Family Tree DNA, that was a yDNA test. My brother also did a yDNA test with Family Tree DNA for us.

Now one of my sisters has tested at Ancestry DNA as well as 23 and me. And another cousin  ( also a cousin to the first cousin) has been tested with My Heritage for us.

  • We recently had the yDNA kits upgraded to include autosomal.
  • I uploaded results from different testing companies to gedmatch.
  • I download from 23 and me to an Excel spreadsheet the data for my matches.
  • I downloaded from gedmatch to another Excel spreadsheet the data for the matches. Some matches were repeats.

So now the tedious task of identifying the family line to attach my matches to.

I’m a very visual person, I like using colors to identify family lines.

 

  • Blue for paternal line
  • Red for maternal line
  • On my spread sheets I added a column for family line.

  • Identify all known matches and then enter the family name in the newly created column.
  • Determine colors and highlight for all lines represented to date on you spreadsheet using the color code.  (I only color code the first column.)

  • Enter on DNA Painter  the known matches, using your color choices.

23 and me and gedmatch allow you to do comparisons of one to many and many to many. Now this may help you identify a few more lines. If you match subject A on chromosome 12  a large segment from say point c to l and subject B matches both you and  subject A within that same segment somewhere between c to l, does this mean that I can now add them to that line, maybe, but let’s do a little more due diligence.

Do they have a tree on gedmatch?

if they do not you may still be able to find a tree online.

On gedmatch the kit number for your matches indicate the source testing company.

M = 23 and me original (new kits have to be uploaded to gedmatches genius series.)

T = Family Tree DNA

A=Ancestry DNA

H = My Heritage

If you have a subscription to either Ancestry or My Heritage you may be able find their tree on line. If you also tested on the same site you will have access to their tree if it is  public. If not one of the clues may be the name they associate their data to. Often we use the same name or email handle across all formats.

Find their tree and or a list of names on their tree.

  • Look for names that also appear in your tree.
  • If they are a 3x to 5x cousin check location for their 2x to 4x great grandparents if determinable.
  • Contact them to determine and establish relationship.

Cautions

  • Just because they have a Ferguson in their line and you have one on your maternal side also, does not mean they are one of your Ferguson’s. They could actually be genetically related to you on your paternal line. Do not be quick to jump to conclusions. Look to see who else they match that you match.
  • When you have two matches that also match each other, check further they may not relate to each other on the same line. Similar to above but their relationship is just coincidental.
  • Again do your due diligence.

Progress on my objective?

 Objective in Identify the maternal yDNA line, in order to determine who genetically our 2nd great grandfather was.

  • All the matches I have identified to date are mostly on my Paternal line.
  • Those on my maternal line to date are on my mothers mothers line.
  • I have tried contacting by email 2  third cousins on my family tree from the maternal y line. No response.
  • No success in Identifying any second cousin relationships on this line.
  • Yay! Found and solved one brick wall on my Paternal line.

I could use a few suggestions from you on how I might proceed.

WDYTYA ~ Seeking William L. Dougherty descendants

Who do you think you are? Does this really change after you do a little genealogy research? How about after you get those DNA test results? I thought I knew a lot about who I am. My family was a normal dysfunctional family. We had our rascals and sweethearts. We knew what poverty and wealth looked like. I knew what I did and didn’t want my life to turn into. But who were my people? Maybe that is the question I keep asking and why I still love genealogy. I have learned so much of history and the world. I was not looking for connections to greatness (well maybe at first) and I was not surprised to find just the common folks. But they are still very interesting people that I have discovered. Now I am delving more into the DNA of my family lines and it is interesting and daunting. My motivation was to solve our Brick wall. William L. Dougherty. Click on William’s name to see my earlier blog to learn more about him.

DNA testing
I took my own DNA test back in 2013 with 23 and Me. Gosh was it really 5 years ago. It has not solved my brick wall. I have found lots of connections and we did solve one other brick wall. But not “The One” I was looking for.

So now comes the daunting or maybe tedious work. Finding those collateral descendants who will help us move backward in time.

Who was William L. Dougherty?

Click to enlarge.

The idea is that we need to duplicate our ancestors DNA. The yellow highlighted individual s  the ones that I have. Those with a red dot I am looking for and the orange highlighted ancestor is my target ancestor. The idea is the orange target ancestor gave 50% of their DNA to their children (the next tier to his left) and not the same 50%. Their children gave 25% of the targets DNA to their children (the next tier moving left) and again not the same 25%. The next generation only gets 12.5% of the targets DNA and again not necessarily the same DNA. So my generation only receives about 6.25% of the targets DNA. So ideally if we had 16 descendants tested we may be able to come close to duplicating our targets DNA. That’s a simplified illustration. (Theoretically we could hope to approximate a facsimile of our ancestors DNA but with the endless variables it will be statistically near impossible.)

Start the search

Who is there out there that falls into those boxes?

  • My parent only had two siblings. So my grandparent is as well covered as possible with 5 cousins tested.
  • My grandparent had 6 siblings. 3 died before reaching 10 years of age. Two sisters had children, in this group there are four 1st cousins once removed. I doubt that any here are still alive so I will look for their children &/or grandchildren. The grandchildren will only have 3.125% of targets DNA. Unknown # of 2nd. cousins
  • My great grandparent had 4 brothers. Some time ago I had been contacted by the descendants of one of the brothers. In the mean time we have moved and I lost contact. So I will try to find them again. Of the other three brothers I know of no children. Only one other ever married and I have not as yet found any children for him. That would be a possible 12 3rd cousins.

I will be reaching out to those known to me and see if they have tested or are willing to be tested. So if you are a descendant of William L. Dougherty and you are interested in solving the mystery of who William L. Dougherty was please contact me.

 

 

DNA and Ethics

I had my DNA done early, March 2013 with 23andMe. It seams like it was a lot earlier than that. I really liked the information I received and found their website relatively easy to navigate. I made a few connections back then, but no block busting discoveries. One of our main brick walls was with my mothers surname line.  So my sister and I decided to ask our eldest cousin (we only have three and they are all on that line) to do a yDNA test on Family Tree DNA. Just to round things out we also asked our brother to have his yDNA tested. Since we bought and paid for them we were the administrators.
Since then I decided to upload my DNA results to gedmatch.com. Once uploaded I had an unknown cousin contact me that helped solve a brick wall that my sister had been working on for at least 20 years. But it was not the brick wall for my mothers surname.

Now my sister has tested with 23andMe. Recently I talked another cousin into testing after I won a Myheritage DNA kit.
With all these different testing companies I thought it would be a good idea to get all of the test results on gedmatch.com.
When I spoke to my cousin that most recently tested I did speak to him about gedmatch.com. I also sent emails out asking my cousin and my brother for permission to put their results on gedmatch.com. My brother did ask for further information on what this was, and I explained, after that No response.
So there’s a dilemma.
How do I handle this?
What are the ethics about managing others DNA?

 Getting permission is the correct thing to do before uploading someone else’s DNA to a third party site. The problem is not with them it was with how my sister and I approached the DNA Testing. We were so excited about using the DNA results to solve our brick walls and gain further knowledge about our genealogy we did not take the appropriate steps in obtaining a well thought out form of consent from the DNA contributors.  So now I have developed a DNA Consent Form to fill out and have signed by myself/or sister and our relative that we will be the administer for. Hoping this will ease the mind of those we administrate for and ourselves. I have included:

  • Who is paying for the testing. In the past we have paid for all the testing and updating.
  • What type of test they are agreeing to take.
  • That as administrators that we will make all contacts and handle all inquires.
  • That they can elect to have their DNA sample stored or not.
  • That they will have access to their results.
  • That their contact information may not be shared accept for surname.
  • That administrator(s) may upload the results to third party sites for  possible further matching.
  • That the test taker wants/or does not want to be informed about any unexpected results.

Did I miss anything? If presented with a form that includes these items would you sign?
