​Seraphina's birth place was not mentioned in any of her Russian official documentation. In fact, it was not mentioned or talked about at all.​ The reason for that was the very circumstances prior to Seraphina's birth. ​

​

Seraphina was born a twin in France to Sophie de PRITTWITZ, - a 19 y.o. girl of the Russian aristocratic émigré circles residing in Paris who had a clandestine love affair with Seraphina's biological father, - a Soviet undercover agent who worked in diplomatic services in the French capital. At the time, Paris was a significant target for Soviet intelligence agencies, including the KGB and GRU, which led spy rings operating from the Soviet embassy.

​

​Since Seraphina's parents belonged to different ideologies divided by the Iron Curtain, they could never be married. The children of such a couple had to be given up to the Soviet secret services. However, in those times, prior to the delivery, the gender and the number of children who were expected to be born was unknown. To ensure secrecy and to avoid official registration of newborn(s), a private delivery was arranged by Sophie's family, and a midwife to attend the birth had been hired.

 

Sophie de PRITTWITZ gave birth to heteropaternal twins, - a girl, Seraphina, and a boy, Seraphina's twin half-brother. The fact that the born twins were heteropaternal was discovered much later, at the time when Seraphina did her DNA tests and discovered that she was a carrier of more than one genome, her full twin brother included.

 

For some reason, the original plan of giving up both children to the Soviet system was not realised. Instead, a decision was made to 'sacrifice' just one twin - Seraphina, - and to keep her twin half-brother in France. As a result, Seraphina was not declared to the French authorities (Déclaration de Naissance), only her twin half-brother was. This created a stateless condition for the new born which allowed Soviet operatives to take Seraphina out of France and bring her to Leningrad, USSR, where her status was legalised and official documentation arranged. The legalisation and preparation of the documents happened in the Institute Ott - a research medical institution located in Saint-Petersburg (former Leningrad).

 

Thus, began the 'official' story of Seraphina's birth in the cultural capital of Russia where she spent the next 23 years of her life.
