Post 2 DNA Matches Results in a New Cousin and Then Not a Cousin

The discovery of a “Family Finder” DNA match in October 2017 to two researchers, one not connected with this blog and one which did, led to taking the next steps.
The contact with the first researcher left us both baffled. The only connection she could find with any possible DNA connection was through her maternal Scots-Irish Line. After a restless night, it turned out that that was the only connection I could make as well. See the following post:
Since her Germans came from Pomerania, Posen, and Switzerland and mine came from West and East Prussia, we let the matter drop.
The second match to an early reader of this blog was more surprising. When I brought the connection to his attention, he wrote:
Here is what I discovered:
We show up on each other’s chromosome browser.
We share a small segment on the left side of chromosome 9.
Your sister does not show up on my list of chromosome matches.
My sister does not show up on your list of chromosome matches.
We are not related on my mother’s side since my Kokoschka cousin has nothing on chromosome 9.
We must be related on the Hirsch side because another Hirsch cousin has some chromosome 9 overlap with me, but she does not show up on your chromosome matches.
A fifth cousin match takes us back to my ancestor Niklaus Hirscher born in Salzburg or his wife Barbara Brandstetter who married in East Prussia in 1762 near Ragnit near Tilsit. Their son, Johann Hirsch, is my ancestor who moved to New East Prussia (now Lithuania) around 1800. I think our DNA match on chromosome 9 goes back to East Prussia – no surprise.
Now that we were “fifth cousins” he allowed me to visit “For Family Members Only” part of this website and provided me a “for your eyes only” autobiography. To be connected through research and ancestry because of this blog was rewarding.
I mentioned that I know another East Prussian researcher who lives locally. She is my “go to person” because of her search in East Prussia for her -at name, her knowledge of the German language, and her background in teaching biology at the university level.
The “my new fifth cousin” posed a question:

Can you ask her what is typically found on the left part of chromosome 9 – eye color? hair color? Height? They must have figured out what features each chromosome covers. If I knew that then my other chromosome overlaps with other relatives might be more meaningful.
Quotation marks in her answer indicate exactly what she said.
She had just read an article (which I will forward to you when I get it) about what is called a “pile up.” It is “on the right side” of the center of (whatever technical term refers to the middle) which apparently is better than being on the left side of the middle of the chromosome.
“Lots of people have chromosome 9, in particular.”
Whether this is “important to health, I don’t know.”
Her “husband has a lot of people who share chromosome 9”
You “have to have at least 40 total centi Morgans in common and a chunk the size of 10 or 15” (depending on what you read) “or it is not worth pursuing.” It is “meaningless genealogically.”
It can be considered an “accident” or a “coincidence” or a fluke. My word, but she agreed.
“It is complicated.”
My final comment to “my newly-lost cousin:” Having said all this, would you like your family tree back? Do you want to change the password on your website so I cannot look at it?
His final reply:
I have just come up with my own theory that the section of chromosome 9 that we share has to do with how we think and doggedly pursue inquiry – which is very similar. So maybe that explains our common heritage.
And he signed it “Cousin”

About suwalkigermans

I started family research in 1993. My first two books focused on my maternal grandparents. Both families came from Kreis Rosenberg, West Prussia, to Big Rapids, Michigan. I left the Spurgats from Wylkowiszki in the Russian Empire as the third book because of the difficult and challenging research it required. After I published the book in 2010, I wondered what to do next. I thought I might try to share some of my research with others and maybe at the same time, by going digital, someone would find me. When you read the comments, you will see that happened. The best part of all this is helping others.
