Numerous bases suggest that this seemingly improbable and statistically improbable story is true and she is the lady with most children.

On the day of 27 February 1782, the list from Nikolskiy cloister came to Moscow covering the information that a peasant of the Shuya district, named Feodor Vassilyev, married twice, had 87 kids.

His first wife in 27 quarantines gave birth to 16 pairs of twins, seven sets of triads, and four sets of fours whereas his second wife in 8 confinements gave birth to 6 pairs of twins and 2 sets of triplets. F. Vassilyev was 75 at that time with 82 of his kids alive.

In all, 35 births, 87 children, of which 84 were alive and only three were unsuccessful to live their infancy. It is thought Feodor Vassilyev existed to the age of 75 and his initial wife lived to 76.
