What I believe is that Ruby dos know Yang is her half sister. But with in the social group of Hunters it is a meaning less difference. The fact is that they where raised as siblings.

As I have stated before half siblings may be common with in Huntsman society do to either death of one parent or simply more open view on relationships.

I believe that fostering/adoption of orphans of Hunters by other Hunters that have settled down may also be common as again the mortality rate of Hunters is likely to be severe compared to other dangerous jobs in Remnant. So who you consider your brothers and sisters may include individuals who have no blood relationship with you. It may also be common for other orphans to be placed with Hunter families as where at the least they can learn an honorable profession.
