He named all his children with "V" after the death of his first son

On May 1, 1881, Ivan Pavlov wed Seraphima Vasilievna Karchevskaya, whom he had first met in 1878 while she was attending the Pedagogical Institute in St. Petersburg. Sara, also known as Seraphima, was born in 1855. She fell ill afterward and passed away in 1947.

Financial difficulties plagued Pavlov and his wife for the first nine years of their marriage; they frequently had to stay at other people's homes, and there was a point when they split up to find filial piety. Material well-being is only a secondary concern, despite the fact that their poverty generates misery. Sara miscarried during her first pregnancy. The couple took measures when Sara became pregnant again, and she gave birth to their first child, a boy they called Wirchik, safely. Sara, however, became quite upset after Mirchik's untimely death as a toddler.

The Pavlovs produced four additional children after the untimely, premature death of their first child, Wirchik. One of the Interesting Facts about Ivan Pavlov is that he named all his children "V" after the death of his first son. Three sons and a daughter they called Vladimir, Victor, Vsevolod, and Vera. Just one year before his father passed away in 1935, their youngest son, Vsevolod, passed away from pancreatic cancer.
