If no one has any objections, I will disconnect Sissa Persdotter from her current parents Per Åkesson and Truen Persdotter. The reason is that I see no evidence for this relation to be factual. Also Sissa's mother Truen Persdotter would have had to be 13 years old at the time of Sissa's birth, provided the dates are reasonably accurate. Her sibling Jon is born 12 years later, and in Hästveda, not in Knäred. Her sibling Jon is also born after the only dated birth of the relation between Truen Persdotter and Torkel Sonesson, suggesting Truen had a relation with Per Åkesson, Truen's father, before and after her relation with Torkel Sonesson.
I find this highly unlikely.
