Y haplogroup humor

Esto’s cartoons often really hit the spot. This one really reminds me of my husband and myself.

When I told my 98% Ashkenazi husband that his Y-DNA haplogroup (E1a1 aka E-M44) probably originated in Timbuktu, he started dancing around the room shouting “I am black!”

Using your DNA test results: the Basics for Genealogists

How do you use autosomal DNA testing to enhance your genealogical research without having to take a PhD level course? This is a question several of my cousins have asked me, so here is my attempt to answer.

  • First of all, get as many relatives to test as you can. The more data you have, the easier it is to make useful comparisons and sort new DNA relatives into their related family lines. The closer family members shown in my chromosome map above are all cousins I convinced to test.
  • Secondly, make sure you know how to use a spreadsheet: sorting, deleting rows, inserting columns; you only need to know the easy stuff.
  • Third, check your understanding of how DNA works. Perhaps read my basics page – http://blog.kittycooper.com/2013/04/the-basics-at-23andme/ – and follow up with whichever lessons, books or videos appeal to you among those that I suggest or that you find listed in the ISOGG wiki – http://www.isogg.org/wiki/Autosomal_DNA
    Also lots of beginner questions are answered in the FAQ I keep for the DNA-NEWBIES mailing list on yahoo; a copy is on this blog – http://blog.kittycooper.com/dna-testing/newbie-faq/ – so check there when something is confusing.
  • Fourth, bookmark a page with an explanation of all the acronyms – this is a good one: http://www.isogg.org/wiki/Abbreviations – a key term is cM. You do not need to understand the definition of a centimorgan (cM), hardly anyone does; just accept that it is the best measure of the importance of a DNA match, the larger the better.

Now to the practical application of all this, using shared DNA segment data to find relatives, preferably those 3rd and 4th cousins that your family no longer knows of. Click on success stories on this blog to read about some of the cousins I have found with DNA.

When people are shown as matches to you or your relatives, the testing company will make a guess as to how closely related they are. Beyond 3rd cousins, it is not possible for them to make an accurate estimate because of the random nature of DNA inheritance.

I am traveling to Norway in June

Excitement! I am visiting Norway with a cousin from June 18-26 to walk where our ancestors walked. Any Norwegian cousins I have not already contacted please get in touch if you want to meet up! I will put my exact travel plans, as they develop, at the end of this post: roughly Bergen to Etne to Bergen to Oslo to Drammen to Kristiansand …

I visited Norway in the 1980s. I went to Stavanger for a tournament and I had no idea where my ancestors had lived nor did I think much about it, other than announcing proudly to my hostess that I was descended from King Harald the Finehair, according to a cousin’s research. She gave me a funny look.

Now I know that everyone in Norway is probably descended from that king who lived in 850 A.D. Various mathematicians have proven this concept (see my blog post on how many ancestors for more on that). Since Norway lost about 2/3 of its population to plague in the 1300s, I would guess that everyone who survived that, and has descendants, is an ancestor to all of us of Norwegian descent.

However after almost 20 years of doing family history research, I have learned a great deal about the farms my ancestors lived on and the lives they must have lived. Norway has these wonderful local history books, called bygedebuks, and often referred to as “farm books” which tell you much about the farm as well as everyone who lived there and how they are related. So I am making an itinerary which includes many of our ancestral farms.

Also I was lucky to have ancestors who liked to write, so I have many family stories preserved on my family history site at kittymunson.com – one of my favorites is my grandad’s story of their immigration trip from Kristiansand to Brooklyn, NY.

Lets All Help Collect DNA Statistics

The DNA relationship statistics listed at ISOGG are invaluable for figuring out how you are related to new DNA relatives. This diagram shown there is a big help too:

More statistics would be even better so I am delighted to make the following request.

Genetic genealogicist Blaine Bettinger has decided to collect cM numbers for known close relationships from all of us who have tested. Read about it on his blog and then contribute yours. He wants family statistics out to 3rd cousins.

Blaine explains how easy to provide those numbers if you are tested at Family Tree DNA, but 23andme includes the X in their totals which skews the results. Plus they include segments smaller than 7cM which is not what Blaine wants. So I decided to make a step-by-step how-to for 23andme statistics collection.

Better is if your 23andme or Ancestry.com tested family members are all uploaded to GEDmatch.com. Then you can easily get the statistics there. Just run the one-to-many with the normal default of 7cM for each family kit and look in the columns Total cM and largest cM under Autosomal.
