Martha Eriksdotter

Martha Eriksdotter (Märta Bonde) is said to be the daughter to Erik X, King of Sweden. However, her existence has been doubted by some modern Swedish historians that think she was just made up by Charles VIII or his chroniclers to provide him with a more impressive background.
It's said that she was married to Nils Sixtensson Sparre, a Marshal in Sweden. Martha’s paternity and her marriage are recorded in the book Anteckningar om svenska qvinnor by PG Berg and Wilhelmina Stålberg, Page 274. The title of the book in English is: Notes on Swedish women. (A biographical dictionary from 1864, covering only Swedish women.)
In Swedish the page reads:
Märtha, dotter af Erik X, som blef gift med Nils Sixtensson till Tofta, och, genom detta äktenskap, stammoder för Sparre- och Oxenstjerna-slägterna.
English translation:
"Martha, daughter of Erik X, who was married to Nils Sixtensson of Tofta, and, through this marriage a progenitress strain for the Sparre and Oxenstjerna families.
