The multiple kit analysis function works beautifully with tag groups. Another benefit of tag groups, is that when I don’t remember the kit number of a cousin whose results I wish to view, I can look it up quickly by displaying the people in that tag group (from the View/Change your profile (password, email, groups) on the top left)
My previous post about tag groups mentioned that tag groups are a quick way to see where a new match fits in by looking at their one to many page for your tag colors. However this is less useful for a distant cousin match (fewer colored tags) or an iffy paper trail match. In those cases I put the new person in my Unknown group (which only ever has the one person being analyzed) and then compare with all the relatives I expect a match to, by using their tag groups.
The main GEDmatch page has a box called Analyze Your Data and towards the bottom of that box you can see Multiple Kit Analysis with a big red NEW next to it. The “new” is because you can now use tag groups for this analysis. When you click Multiple Kit Analysis to get to that function, you will see a page like the one shown below. The old way of doing multiple kit analysis, by typing in each one, is still available from the Manual Kit Selection/Entry tab on this page or by checking boxes in various other functions like one-to-many.
My tag groups: note that I am using shades of aqua and blue for my Etne, Hordaland, Norway descended cousins
You can check the tag groups of interest and compare them to the new person (the Unknowns group for me) in all the wonderful ways the multiple kit analysis gives you (Click here for the slides on that from my most recent GEDmatch presentation).
Recently I have been searching for a “Lee Oleson” who is the grandfather of a third cousin match at Ancestry. He was only in town long enough to get my match’s grandmother with child. This third cousin’s one to many lights up with the colors of my Etne, Hordaland, Norway side relatives. So I set myself a project of tracing forward all the descendants of the eight children of my Etne great-great-grandparents to see if I could find Lee.
Having just received the Etne, Norway local history books (bygdebuker) for Christmas, I have spent countless hours looking at my ancestors in them. Naturally I have been trying to think of even more ways to use these books.
An idea that came to me was to look at my Dad’s one-to-many X matches at GEDmatch.com and see if I could find a match where I could follow the lines and connect them to Dad’s maternal grandad via those books
The largest X match he had with an unfamiliar name and email was to *k for 26.8 centimorgans (cMs) and it included a small autosomal match of 6.3 cMs. This seemed promising so I used the user lookup function on my GEDmatch home page and was delighted to see that she had uploaded a GEDCOM.
The GEDCOM number is clickable from the lookup result and it takes you to a page listing the individual. Of course what you really want is the pedigree to quickly scan for relatives in common and there is a button for that at the top of the page. Better is to use the compare 2 GEDCOMs feature from the home page to compare your match’s GEDCOM to your own. Works great if you both have deep trees but I had no luck with that for *k.
Next I clicked on the pedigree button at the top of her individual listing in the GEDCOM which took me to her pedigree page. Nothing jumped out at me and most of them were from Germany.
So what is the opposite of the saying when it rains it pours? How about the sun is not only shining but there are rainbows!
When you keep extensive spreadsheets that include the common ancestor for segments of DNA that triangulate, you sometimes have quick success with a new DNA relative.
I recently shared my Norwegian 3rd cousin’s kit with Shelley on 23andme. She has a large X match with him that I am still working on. His maternal side from Rogaland is not related to me that I know of.
Naturally I always compare a new DNA relative to everyone else possible. I was surprised to discover that she shares a small bit of DNA with my Dad and my brother that triangulates with a known fourth cousin and her sister. Synchronicity … these are the same cousins mentioned in my previous post about my X segment from Ve and Fatland.

So I emailed Shelley and told her that she shares a small (6cM) segment that we know comes to us from our ancestor Aamund Bjørnson Tvedten (Ve) 1772-1842 so perhaps we share one of his ancestors. She replied back, all excited, wow my great-grandmother is Anna Wee (Ve).
Endogamous populations are much harder to work with in genetic genealogy because you have double and triple 6th cousins who look like 2nd to 3rd cousins when you compare their DNA to yours. Ashkenazim (see my Ashkenazi DNA post), Mennonites (see Tim Jantzen’s project), and Polynesians (See Kalani Mondoy”s project) are a few of these intermarried groups. See the ISOGG wiki for a further discussion of endogamy.
A fellow genetic genealogist, Israel Pickhotz, has written a fascinating book about how he has confirmed and refuted many genealogical connections in his extended Ashkenazi family. He did this by testing every cousin he could. That story is an inspiration to those of us frustrated by using DNA to research our jewish roots. It is as easy to read as it can be, given that genetic genealogy is not easy to understand. Lara, blogging at her blog Lara’s Family Search, wrote an excellent description of the book in her review which is hard to improve upon.
Israel’s blog continues his story: http://allmyforeparents.blogspot.com/
Another DNA expert, Jim Bartlett has just written an interesting blog post investigating the math of endogamy at his segmentology blog. As it is titled part I, I am looking forward to part II.
The problem comes when so many cousins marry each other as you go back up the tree that it gets difficult to calculate the shared DNA. Plus once you get past 3rd cousins, DNA inheritance becomes more and more random anyway.
On my Norwegian side, my Dad has a woman “MB” listed as a 2nd to 3rd cousin who upon investigation was found to be a fifth cousin three times and a sixth another time. She shares 49 cM over 4 segments with my Dad and a whopping 141 cM in 8 segments with my third cousin in Norway. That third cousin is related the same way to MB as we are, but he, like MB, descends from a cousin marriage within this group.
My worry is nothing on this trip will match the incredible day we had yesterday in Etne, Hordaland, Norway. The ancestral farms around the lake were so very green with snow-capped mountains behind them and sheep everywhere. The weather was perfect. We had a traditional lamb and cabbage stew lunch with the Skjold third cousins on their deck overlooking the valley and lake. Followed by fruit-filled waffles.
Jarle at the Lake
Our cousin Jarle was a wonderful guide. He showed me the house, still there, where my great grandfather H. H. Lee was born on farm Skjold. He mentioned that they had shown cousin John the wrong farm, the newer Skjold farm built by Jarle’s grandfather.
The house my great-grandad H H Lee was born in
Jarle also told us that the children called the white plastic wrapped hay bales “tractor eggs” because they came wrapped that way out of the backs of the tractors. Also we learned that most of Norway’s electricity is hydo-electric and that there are green chemicals available for fracking but regulations in the USA are such that companies do not have to use them. He works in the chemicals for oil companies business by the way.
