added to that basically any theory with the word "genetics" in it.

e.g - this person has the same: hair/eye/clothing colour, kind of semblence = THEY'RE RELATED.

- this person has black/white/red/red-yellow in their colour scheme = GRIMM HYBRID

And then the Ruby-Yang family theories... (on top of ones already mentioned)

- Raven's the mother of both girls, Neo's a sister/mother to one of them (aka Neo is Summer Rose or her daughter), Ozpin is Ruby's dad/grandad, Taiyang was in a polygamous relationship with Raven and Summer.
