It better not be a direct decendant, it's not canon that Obi Wan had any kids, and it'd be totally out of his character because he was so damn "Old Order" Jedi he shat Yodas. (And yes, you're now picturing Old Ben Kenobi with Yodas flying out of his ass giving that little laugh of his). No way would he have screwed a female on the side.
Aside from it being out of character to have a kid, this reeks of throwing in a character for name recognition to get asses in seats. Abrams did all that shit in Star Trek... ("Tribbles and Green girls, they'll remember those, let's put em in!")
Disney also has a nasty habit of targeting demographics for Maximum Moichanising [http://images3.static-bluray.com/reviews/1526_3.jpg], and they're milking their existing princess stable for all they're worth, eager to add more.
Disney and Abrams are a danger to the franchise as much as Lucas, but in a different way, all the characters could be "supercharged and screaming" like in Star Trek. Hopefully, all the people they're bringing in from the original movies can tell them "No" when they need to hear it as they did during IV to VI.

She certainly looks like a strong confident person in that picture of her, rather than cutesy damsel in distress, so that's something to look forward to.
My ideal situation would be to see her kick Solo in the balls for calling her toots or something.
That was Leia in the originals, but the sarcastic smart-ass tough girl character is such an overused trope it's really painful to see if they aren't written correctly, but Abrams isn't subtle about character traits at all.
