Because of debts the Chodkiewiczes owed to the Radziwill family, it became expedient to make a match between Sophia and Janusz Radziwill, Prince of Nesvizh and a son of the governor of Vilnius, Prince Krzysztof Radziwill. At this time Sophia was eleven years old.[1] The wedding between Sophia and Janusz was scheduled for February 6, 1600 in Vilnius.
