This question has been bugging me for the longest time. How exactly is Ruby related to Taiyang? I know he's her daughter and all...but how?

This wouldn't be such a big deal, but Ruby took her mother's surname, so she's Ruby Rose not Ruby Xiao Long.

So, here's my questions...and yes it is plural: Is Ruby Taiyang's daughter by blood or by marriage? Were Taiyang and Summer even married? These last two only depend on how that first question is answered: was Ruby born before Taiyang and Summer got together? And if she's not Taiyang's by blood, who is her father?
