Although there is some question as to whether Yang and Ruby's father is 'Taiyang' or 'Tai Yang' and Yang, like Ren, is known by her family name. Personally, I think that the latter would open too many naming inconsistencies just within the subset of the two of them, so I'm going with their father's forename being 'Taiyang'.
