English and British Royal names from 1066

Sancha of Leon was an 11th century princess who became Queen of Spain after her brother was killed by Ferdinand I, whom she then married. A twisted tale indeed, but Sancha is one of those names that is both historic and extremely rare -- no babies were named Sancha or Sancho in the US in 2021. Sancho Panza was the sidekick of the fictional Don Quixote.
