Mrs. Vassilyeva and her husband Feodor Vassilyev were peasants living in Russia in the 1700s. While being married to Feodor his wife gave birth to 4 sets of quadruplets, 7 sets of triplets and 16 sets of twins or a total of 69 children over a period of 40 years. Reportedly, all but two of the children reached adulthood. Feodor also had two sets of triplets and 6 pairs of twins with his second wife which means he fathered 87 children altogether.
The story of Feodor Vassilyev first became known to the public after The Gentlemen’s Magazine published an article about him in 1783. The magazine was sold in England and the story reached the United Kingdom through an English merchant who lived in St. Petersburg and wrote about Vassilyev to his relatives. The French Academy of Sciences also mentions Vassilyev and his many children in a 1878 article about twins. The Guinness Book Of World Records acknowledges Vassilyev as one of the men who fathered the most children.
