Katarina (Erikska ätten) - okändare of sådana Katarinor

[M.Sjöström]

There are genealogies floating around which postulate a daughter Katarina Eriksdotter to king Eric X of Sweden.
 
The said Katarina Eriksdotter is mentioned having first married a Peter Laurensson, and of that marriage possibly got sons:
- Lars Petersson, justiciar of Ostrogothia, the one who abducted Benedikte Sunadotter in c 1245 from Vreta, and himself died well before 1251 revolt, 1250 accession of king Valdemar, and probably already before 1248 revolt. He as person and Filip's (below) brother is well attested.
- Filip Petersson, who took part in 1251 Folkunge revolt, and was executed in that year. He as person and Lars' brother is well attested.
 
Katarina is mentioned as having (secondly) married Magnus Broka, and that Knut Magnusson (Knut Katarinason), a pretender with the 1251 revolt, was the child of that marriage. Magnus Broka and Knut are well-attested as having existed and being father and son.
 
Now questions:
 
- is there actually any credible evidence about any adult Katarina being daughter of Eric X ?
- who was this Katarina's mother ?
- what is known about who was Filip Petersson's and Lars Petersson's mother?
- what sort of evidence exists that Knut, son of Magnus Broka, was ever known as Knut Katarinason?
- is there, rather, credibler evidence that Magnus Broka's (one) wife was king Canute I's daughter? what evidence?
- is there, rather, credibler evidence that Knut, Magnus Broka's son, was actually son of king Canute I's daughter? what evidence?
- is there evidence at all that Peter Laurensson was married with a Katarina (even if she possibly were not Lars' and Filip's mother)
- what are the two mentions in Swedish chronologies (obs! apparently not chronicles, but kronologier) of this sort of Katarina? where? what do those mentions read actually?
- is anything known how old were Filip Petersson and Knut, when the 1251 revolt took place?
- how probable is that there existed this sort of Katarina who however was not Eric X's daughter?
