Eric X of Sweden
Erik Eriksson, calledErik the Lisp and the Lame. He was born in 1216 after his father's death. The Karl Chronicle says that "Erik Lisp and Lame" also had a sister, Martha Farmer. This would have been Erik Knutsson's daughter. Historian Dick Harrison says that this is only political propaganda for Martha's cousin, Karl Knutsson (Bonde). This untrue connection would have made him a relative of the House of Eric.
