Found a 3rd cousin in Norway via DNA!

A Norwegian, who turned out to be a descendant of my gg-grandparents Jørgen Wold and Anna Knutsdatter of the Drammen area, tested his DNA on 23andme and came up a close match (3rd-5th cousin) to my Dad with 35 cM over three segments of matching DNA (0.48% shared). Most matches called 3rd to 5th have been just two segments and have turned out to not be that close but rather to share two ancestors. However Henrik was on GENI.com and an exploration of his tree found that he was descended from Jørgen Wold’s daughter Olava. This is the first time it has been so quick and easy to find a relationship! He is much younger than I am, so two generations further down the tree. Naturally I had to use the new DNAgedcom feature where I could compare him to all my shared profiles and see who else he matched. Here is the plot of his matches with my family and the larger shares (surnames removed for privacy except from my Dad and brother) created with my DNA segment mapper tool:

Results for a second cousin on the Skjold line

The results for our second cousin John who shares Skjold and Wold ancestry are just in today at 23andme so of course the first thing I did was compare him to me, my brother, my dad, and a few other cousins. Interestingly John has inherited far more DNA in common with us than our Munson side 2nd cousin has.

Dad shares 608 cM over 25 segments with John and only 389 cM within 18 segments with Dick, our Munson 2nd cousin. My brother shares 281 cM over 13 segments with John as opposed to 155 cM over 7 segments with Dick while I share 282 cM in 15 segments with John as opposed to 175 cM within 10 segments with my Munson 2nd cousin Dick.

Here is a pretty picture I made with my chromosome segment mapper tool:

My Double 3rd cousin versus my brother and my Aunts as shown with my segment mapper

The results came in for my other maternal Aunt so now there are four of us to compare to my double third cousin and still no match on the X! In order to show the comparisons I used my new nifty chromosome segment mapping tool and also added in a bunch of known 5th and 7th cousins to the diagram.

Results in from my Double 3rd Cousin!!

According to family lore, when their business needed money my great-grandmother Charlotte Langermann Thannhauser, on my German Jewish side,  fixed up her sister Lina with her husband’s half brother in order to get Lina’s dowry invested in the family enterprise. Not such an uncommon occurrance. I was able to convince Lina’s great-granddaughter on the straight maternal line to test at 23andme. She is almost doubly my third cousin, sharing DNA from the Thannhauser and Langermann lines but not Engel.Dbl3rdCousin

We have results from a first cousin

One of my cousins (half Norwegian) on Dad’s side (all Norwegian) just got his results. So I made this chart comparing myself to my 1st, 2nd, and 3rd cousins on Dad’s side. Mind you, the 2nd cousin is on Dad’s paternal side while the third cousin is on his mom’s side.

My brother’s chart looks very similar except no X match of course. Notice the very large X match I have with my first cousin which would come from his mother and my Dad’s mother, 57.3 cM. Interesting to see this as compared to my Dad ….
