In 1885, Xavier, A young Austrian blacksmith has left home to raise it. After finding a new job abroad, Xavier, a Gentile, falls in love with Diner, the 17-year-old Catholic-Jewish daughter of his boss. He was later fired. But that was just the beginning of the family drama.

Dina ran away from home to live with Javar, and Ron, a 30-year-old Jewish factory owner, found a place to stay and work. In 1887, she gave birth to a son, named Rank, who is believed to be Ron’s father. Rank adopted Jewish rites and was baptized in a Catholic church.

But Dina and Java were together, and after Java had some success in her career, the two were married in 1889. Javar acknowledged the then-one-and-a-half-year-old Rank as his step-son and supported Ron. Family. Xavier and Diner had three more children, including a boy named Arles. During World War II, Rank’s entire Jewish lineage was kept secret, while he and his relatives lived in fear of being deported to concentration camps.

The secrecy of his paternity was maintained in public for years, but the real identity of the father of rank in the family has been passed down from generation to generation.

Cordula Haas, a forensic geneticist at the University of Zurich in Switzerland, was approached with an unusual request and moved quickly to May 2017. Descendants of Rank and Arles wanted to verify that Ron was in fact Rank’s real father. The family offered to wash the cheeks from the surviving descendants of Dina, Rank, and Arles for DNA analysis, and হাস at the request of Haas-some postcards sent by Rank and Ron that contained their DNA in the remains of used saliva. To paste the stamp.

Resolving kinship cases is a common task in forensic genetics, but this case was a little more complicated than laughing. For a year and a half, he and his team tried to confirm the story, to no avail. By October 2018, they had dropped the towel. But then, in March 2020, the family returned, this time with more inheritance. They found some more old postcards that Earls sent on a business trip in 1922.

Scientists have compared the DNA found under the stamp of this card with the DNA found on a postcard sent by Rank when he was fighting in World War I and on a post-war tour. They found common Y chromosomal lineage, meaning that two brothers shared the same father. More than a century later, the family ended their paternalistic drama: Javar, not Ron, was Rank’s father.

With the consent of the family, Haas and his colleagues detailed their investigation Paper Published in the journal this month Forensic Science International. (All names were changed at the request of the family.) And while this may seem like nothing more than a fun ending to a family mystery, extracting centuries-old DNA from artwork ফ্ল flapping a licked envelope, hair from an old brush was once considered The next big thing In genetic heredity. The promise is to give someone a chance to gain valuable insights into long-dead ancestors and loved ones, to look further back at their family tree, and to make possible reunions with existing relatives.
