Autosomal DNA testing confirms a suspected WOLD relationship!

A long time ago I received an email from the husband of a possible cousin wondering if his wife’s WALD family was the same as our WOLD family. Naturally I suggested a DNA test and the results just came in. Yes she is a member of our WOLDs and is descended from my gg-grandfather Jørgen Oleson Wold via my g-grandmother Maren Wold’s brother Carl (Charlie) Wold. Below are the faces of four generations of my new 3rd cousin once removed’s ancestors.

A deep DNA triangulation success story

So many of these one segment DNA matches that I find with other testers are too far back to find the common ancestors. However those of us with Norwegian ancestry often have very deep trees thanks to the good records and the many farm books for each locality. So when you find a fellow genealogist with Norwegian roots who matches your DNA you get quite hopeful, and sure enough …

I had four matches, the colored lines in the picture below, for my Norwegian descended Dad on chromosome 16. However they span the centromere which is from 35335801 to 38335801, so initially these segments did not seem that promising.

Luckily the most recent match had an extensive tree of which only a small piece was Norwegian. So perhaps it would be easier to find our common ancestor with less tree to look through. Note that using a tool to compare Norwegian GEDcoms does not usually work so well because of differences in naming conventions (patronymic, farm name, Norwegian characters, etc)


Here are the details of these segment overlaps from my master spreadsheet for Dad:

Edith 16 31000000 52000000 9.20 1301
Nancy 16 31000000 54000000 9.70 1359
Loretta 16 31000000 52000000 9.90 1423

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:
