Who is this "Poe" guy, the pilot, could he be a love child??

There is a comic series about his parents.

Do you need to add a spoiler on/off in the OP?

I want to ask questions, but can't without spoilers...how long do we need to even worry about spoilers?

I can say: they changed the script after he was cast...big change...makes me wonder what his story is.

I think trying to tie him into some blood line would be trying too hard and kind of soap opera-ish. Talented people in the galaxy come from more than a handful of families.
