Contrary to the movie script, Lyudmila was already married and had a son before war.

Lyudmila Mikhaylovna Pavlichenko was born on July 11, 1916, in Belaya Tserkov, Vasilkovskiy uezd, Kievskaya guberniya, Russian Empire [now Bila Tserkva, Kyyivska oblast, Ukraine]. She died on October 27, 1974, at the age of 58, in Moscow, RSFSR, USSR [now Russia]. The total of her confirmed kills during World War II was 309, including 36 enemy snipers.

In late 1942, Pavlichenko was sent to Canada and the United States for a publicity visit and became the first Soviet citizen to be received by a US President when Franklin D. Roosevelt welcomed her to the White House.
