When Mary Queen of Scots was sent to France to marry the dauphin (crown prince) in 1548, four highborn Scots girls all named Mary or Marie went with her - Flemington, Livingston, Seaton, and Beaton - the four Marys. However, the incident is thought to have occurred in Russia at Czar Peter's court in 1718,where a Mary Hamilton was pregnant, killed the child, and was executed. [From Child]
