1) The book Ludzie z Nawsia also contains genealogy trees, but i see no information about her husband and if she had at all.
2) Dont know about them. I found on Ellis Island only Anthony Fraczek from przedmiescie and few other people.
3) I didn't notice Aniela Wronek in a book. I found an Ellis Island manifest, i read it as she was going to her uncle Jan Krajewski.
Paul Jablonski (and his family) was going to his sister Katarzyna Soltys as written on manifest. Well.. im not sure if i read polish words corectly.. but sentence in book could be also read as Katarzyna (maiden Jablonska) married Anthony Soltys (not Kazimiera Fraczek and Anthony Soltys). If she emigrated before brother Paul thats why we see Paul coming to sister Katarzyna Soltys. Would it be like this?
Many surnames repeats in a books, i can't say who is related to who. I advice buying both books, or letting me give some time, maybe i can still borrow "Włodarze przedmiejskich Łanów"
Edit: Actually i visited a library and borrowed few books. Success!, there is described lineage of all your families in book Włodarze przedmiejskich łanów. For the time being before you order it, i can send you a copies of relevant pages.
Still a mystery of Katarzyna and her son is unresolved - i cant find their manifest on Ellis Island. Maybe they have gone other route to USA. Have you checked here on Ancestry?
