Valentina Vassilyev and her husband Feodor Vassilyev are alleged to hold the record for the most children a couple has produced. She gave birth to a total of 69 children – sixteen pairs of twins, seven sets of triplets and four sets of quadruplets – between 1725 and 1765, a total of 27 births. 67 of the 69 children were said to have survived infancy.

Allegedly Vassilyev also had six sets of twins and two sets of triplets with a second wife, for another 18 children in eight births; he fathered a total of 87 children. The claim is disputed as records at this time were not well kept.
