I really don't want her to be Luke's daughter either and I am quite hopeful those involved have thought this all through meaning she won't be!
I guess we are so used to almost every character in Star Wars having some kind of family connection that it's hard not to assume she is a Skywalker after seeing TFA.
I'm hoping we get a surprise with Rey's back story, I don't mind if she's related to *someone* but it shouldn't be Luke or another main character and if she isn't related to anyone we've met before then that's totally fine too! I don't think she needs to be the offspring of anyone important so far for the film/story to work but arguably as the force is stronger with certain characters it's a safe bet there will be a link to some powerful jedi/force user somewhere.
