A MULTILINGUAL BLOG ON GENETIC GENEALOGY
When Christopher Tapp was declared a free man again, one of the first people to give him a hug was Carol Dodge. In 1998, he was sentenced for the murder of the 18-year-old Angie Dodge – Carol’s daughter. The young man, however, was completely innocent, but it would take more than 20 years until his…
All companies that offer DNA testing for genealogical purposes also provide their customers with their DNA raw data files. Thus, depending on your interests and experience, this data can also be used for other things, such as learning a little more about your genetic predispositions. In addition to various third-party services that can analyze your…
Thanks to genetic genealogy something incredible has happened last Sunday! And I would have given anything to share it with my grandfather! However, during his lifetime people didn’t even dare to dream about the things that are possible today. I hope that my personal experience will not only show how valuable DNA can become for…
In my last post, I’ve written about discovering hidden recombinations on the X-chromosomes of my father and his siblings after comparing them to a distant cousin match. This has raised several questions: Are there more? Where are they? How many of my previous Visual phasing results are incorrect because of hidden recombinations? Visual phasing is…
It all began when the data of one distant cousin messed everything up by not fitting into the visual phasing picture I’ve previously created for my father and his siblings. It ended with a discovery of a so-called hidden recombination (more than one actually!), a situation when your visual phasing results turn out to be…
Last updated on July 19th, 2023. Today I accidentally stumbled upon the baptism record for Marie Lorgueil. She was born in Bordeaux on June 15th, 1634. The record was found by Gilles Brassard. (No, not the famous quantum physicist, but a fellow Québécois now living in Paris.) Last updated on Jan 27th, 2023. All sentences…
Last updated September 5th, 2023 After a thorough research at the archives it turned out that my grandmother and her second cousins share 6 out of 8 great grandparents! This is called endogamy. One generation further, my grandmother’s cousins encounter what is called pedigree collapse as Johann Martin Meier and Anna Elisabetha Wolf appear twice…
If you have the possibility to test three full siblings, then the next great thing you could do with your DNA results is to try out the Visual Phasing technique developed by Kathy Johnston. It allows you to map the segments of your chromosomes to your four grandparents (without having them or your parents tested)…
