My DNA Results – How do they compare to my tree? (Updated)

Screen Shot 2017-05-06 at 5.52.56 PM

Yesterday I shared my ethnicity percentages based on my tree.  They look a little something like this:

  • 62.5% – British Isles (English, Mixed British Isles, Scottish, Welsh)
  • 15.6% – Europe West (French Canadian, French)
  • 9.4% – Scandinavian
  • 6.3% – Some mixture of European Jewish & Italy, Greece
  • 6.3% – Iberian Peninsula (Spanish)

As you can see from my screenshot up there, I have some interesting differences between my tree and the DNA I inherited.  Here is a comparison of my tree ethnicities and my DNA ethnicities.

Ethnicity comparison - Sheet1

The first important note is that those trace ethnicities, 2% or lower, are often considered noise.  In my case, those bottom three surprise ethnicities are not backed up by documentation.  The first six however, are documented, even the 1% Iberian Peninsula.

The biggest surprises for me are these:

  • How little of the French and French Canadian DNA I inherited.
  • How much European Jewish DNA I inherited.
  • How much Italy, Greece DNA I inherited.

John Costello and his ancestors make up 12.5% of my tree.  And yet, I inherited 19% of the three regions he could have contributed – Iberian Peninsula, European Jewish, and Italy, Greece.

And here is where I need to beef up my learning, you see something I read recently caused me to misunderstand a very important point – you inherit 50% of your DNA from each parent, beyond that, it is a random mixture of all that came before them.  I had a handful of paragraphs with some interesting questions and insights into some of the nuances of my tree.  But those questions and insights were based on my misunderstanding, so I chopped them out.  😉  Thank you Deborah for some helpful pointers!  (See her comment below).

I have so much to learn about genetic genealogy.  I need to test my siblings and cousins so I can isolate the various pieces of my DNA and do some fancy-science-y-ultra-nerdy-but-oh-so-cool-DNA-genealogy like this.

While I am still learning, and not completely sure of what my next steps are, the thing I keep coming back to is… How can I be 10% European Jewish when I had no idea I had ANY European Jewish ancestry?  10%.  That’s a lot of percent.  Especially when I didn’t see it coming.

This DNA stuff is oh-so-fascinating.  Have you tested?  Did you find any surprises?

Happy Wednesday, I hope you make a fantastic genealogy discovery today – DNA or otherwise!

My Ethnicity Fractions – Based on My Tree

Scanned Image 101240003

Years ago my younger brother Derek asked me, “What are we?

He was curious about our ethnic makeup as so many people are.  All those years ago I did a quick calculation based on the research I had done and drew up this little map for him.  Over time I have learned more about my heritage and can now update that set of data to reflect my most current understanding of our tree.

ethnicity percentages

Based on this new chart, our ethnicity percentages – from our tree – are:

  • 34.4% – English
  • 12.5% – Mixed British Isles
  • 12.5 % – French Canadian
  • 12.5% – Scottish
  • 9.4% – Danish
  • 6.3% – Italian Jewish (I don’t think this is really a thing, but I’m not sure yet what to call this portion of my tree…see here.)
  • 6.3% – Spanish
  • 3.1% – French
  • 3.1% – Welsh

I know that totals 100.1% – I rounded.

Based on how Ancestry DNA lumps things together, these percentages should look like this on my Ancestry DNA ethnicity estimates:

  • 62.5% – Great Britain (English, Mixed British Isles, Scottish, Welsh)
  • 15.6% – Europe West (French Canadian, French)
  • 9.4% – Scandinavian
  • 6.3% – Some mixture of European Jewish & Italy, Greece
  • 6.3% – Iberian Peninsula (Spanish)

But here’s the thing about DNA.  We don’t inherit exactly half of what our parents inherited.  We inherit a unique combination of half of what they inherited.  So while the percentages based on my tree look one way, the actual DNA I inherited is an entirely different matter.  I have four siblings.  Each of us inherited different combinations of our parent’s DNA – half from each parent, but a unique and random half.

My DNA results are in.  I will share them tomorrow.  They are fascinating.  The portion I am most curious about happens to be the potion that is brand new to me – the Jewish ancestry of John Costello.  What combination of DNA did he pass on to me?  12.5% of me comes from him.  Based on what I know, he could have given me DNA from these three regions – Iberian Peninsula, European Jewish, and Italy, Greece.  Because the Jewish portion is a brand new – weeks old – discovery, I wonder if I inherited any of it?  If so, how much?

Care to take a guess?

Tune in for my DNA reveal tomorrow.

“We’re not Irish… so we just decorate for Easter.”

IMG_6758 2

A few weeks ago, my darling little 5 year old was playing with a friend.  They were in my piano room and I was in the next room.  I heard my kiddo say, “We’re not Irish.”

It’s true.

But, it’s a weird thing to say.  Especially when it’s completely out of the blue like it was.  I chuckled to myself and thought, “Okay, I guess he’s the son of a genealogist.”

Then he said, “So we just decorate for Easter.”

Oh!

Then I got it.

He was basically explaining to his little pal, who could not have cared less, why we didn’t have any St. Patrick’s Day decorations up, but we did have Easter decorations up.  Not lots, just those little window clings.

It was only the week before that my kiddo was at a different friend’s house where there was lots of St. Patrick’s Day decor.  When we left he said we should decorate for St. Patrick’s Day and out of laziness I replied, “Well, we’re not Irish, so we just decorate for Easter.”

My words came right back to me.

But for a brief moment I thought my little 5 year old cared about his ethnicity estimates.

😂

Maybe one day!

 

Happy Tuesday – I hope you make a great, or at least amusing, genealogy discovery today!

 

ps – Won’t it be funny if my ethnicity estimates show that I am a wee bit Irish?

Awaiting the DNA results

I have been learning about the various DNA test options for a few years now.  I finally felt confident enough to decide which tests to purchase for specific family members.  The RootsTech pricing was a great opportunity so I purchased 5 kits.

  • Ancestry kit 1 – For my Mom.  I chose this kit for two reasons – the price was $49 (regularly $99), and because her mother and brother have both previously tested with Ancestry.  This will allow me to compare their results and look for differences.
  • Ancestry kit 2 – For me.  I chose this kit for the same two reasons as I chose the kit for my Mom.
  • Ancestry kit 3 – For my friend who watched my 4 year old during the day while I was at RootsTech.  They have a juicy little mystery in their tree and they know just who to test.  🙂
  • FamilyTree DNA Y-DNA kit – For my Uncle.  His Grandpa, my great grandfather, is a brick wall.  I can’t wait for these results!  I have been trying to find a way through this wall for years.
  • FamilyTree DNA autosomal kit – For my Grandma.  She has already tested with Ancestry.  Her great grandfather was born in France and immigrated to America as a child.  He is also a brick wall.  Because more Europeans test with FT DNA, I am hoping to make some connections.  I also chose this company for her because they store the sample for 25 years.  Grandma is in her 80s, if I decide to retest her sample in the future I can (if the sample is still good).

I took my test and mailed it on Thursday of last week.  On Friday afternoon I got an email saying that my sample was received.  Wow, so fast!  Now to wait 6-8 weeks for the results.  Or longer.  They sold a lot of $49 tests at RootsTech, I’m guessing that their lab is a bit behind.

My Uncle’s test was received on March 8th.  We have another month or so to wait.  Won’t we all be surprised if he matches a different surname than we are expecting?  That is a distinct possibility.

I have mailed the other kits to my Mom and Grandma.  More waiting.  Hopefully they test and mail the samples very soon.

While I am waiting, I need to start studying the book I purchased at RootsTech that was recommended by Tom Jones.  He is basically a genius, so I followed his suggestion.

It is so exciting to begin a new genealogy journey!  I can’t wait to see what I can learn.

 

Happy Monday, I hope you make an awesome genealogy discovery today!
