My usual plan of attack with situations like this is to record what I know to be fact in the information boxes of a profile...and in the Bio. Everything else belongs in Research Notes.
LNAB should be based on your best/earliest primary record, and your Marriage record would say it is Goddard. You have doubts about that based on other unsourced info you have seen. You don't seem positive that the publication you list supports the LNAB being Pares/Pears, suggesting you need to review it for reliability.
If you have enough doubt about her maiden name being Goddard or even Pares/Pears... using Unknown while you work it out is appropriate.
Write a good explanation in your Research Notes about why you are not ready to accept the LNAB without further proof. And why you have connected parents (Charles Pares and Sarah Wootton ) - or you could explain why you disconnected them while you figure things out.
My two cents worth, I'm sure we will hear from others about this as well.
