Who is Ruby Rose's father?


The [Wikia](http://rwby.wikia.com/wiki/Taiyang_Xiao_Long) says that Taiyang
Xiao Long, Yang's father, first married Summer Rose, Ruby's mother. But why
isn't Ruby's name Ruby Xiao Long? This might mean that Ruby isn't the real
daughter of Taiyang, probably his adopted daughter.




TaiYang Xiao Long is both Yang & Ruby's father.

Yang's mother is unnamed as of Season 2. Ruby's mother is _Summer Rose_ , who
is Yang's step-mother.

I have two theories as to why Ruby is Ruby Rose not Ruby Xiao Long.

**Theory 1**

Summer Rose was insistent that her name be carried on, and so Ruby was given
the surname Rose. As [Memor-X has said in the
comment](https://anime.stackexchange.com/questions/14685/who-is-ruby-roses-
father/44727#comment19084_14685), a husband taking a wife's surname isn't all
that rare nowadays.

**Theory 2**

It was a convenient choice for the writers - _Ruby_ and _Rose_ are both very
vividly red items, whereas Yang Xiao Long can be translated as _Small Dragon
of the Sunshine_ or _Little Sun-Dragon_ , reflecting Yang's powerful, fiery
personality & battle ability quite well.

Theming the characters with their colour seems to be quite important in _RWBY_
\- For instance, check out their pajamas below - Yang has a fiery heart on her
tank top, whilst Ruby has rose-patterned bottoms.

I suspect we may find out more if/when Yang's mother's identity is revealed.
