Margareta Leijonhuvud died in August 1551, and a year later, in August 1552 king Gustav Vasa (age 56) married the 17-year old Katarina Gustavsdotter Stenbock, who was the daughter of of Margareta's sister Brita. At that time Erik was two years older than his new stepmother, and the oldest of Katarina's cousins/stepchildren, Johan, was only two years younger than her.
