14% of medieval parents chose "William" for their boys

Prince William of England has something in common with many medieval boys: his name. A new study shows that "William" was the most popular name for boys in the 13th century.

The Henry III Fine Rolls Project at King’s College London has researched personal names from the 13th century Fine Rolls and compiled a list of the most common names for boys and girls. William scored highest for boys with 14%, while women showed a much greater diversity of names with no clear winner.
