Yuri Andropov
His earliest documented name was Grigory Vladimirovich Andropov-Fyodorov; he changed it to Yuri Andropov only several years later. While his original birth certificate disappeared, it was established that Andropov was in fact born in Moscow where his mother had been working in a women's gymnasium since 1913 throughout 1914 and until 1917.
Yuriy Andriyovych Sydorov
Sydorov was born on January 16, 1983 in Rostov on Don, Russia. His father was a military man, and his mother served as a paramedic. In early childhood Yuriy's father was frequently reassigned, and his family therefore had to move about over and over.
