Is Qrow Ruby's dad?

I'm just going to state some facts here (yes I know Monty said Ruby and yang are sisters) Yang looks like a perfect mix of Raven and Tai. Ruby looks nothing like Tai, but she oddly resembles Qrow. Also, her and him dress similarly, fight similarly. Her and Qrow even have matching sliver crosses. Qrows semblence is bad luck, and I have a sneaking suspicion he was terrified to be a dad because of it. But he still hung around Ruby a lot. Even when compared to yang. He taught her how to fight and helped her make her weapon, And he always always looks out for Ruby. At the end of season 3, he is the one who goes after Ruby while Tai satays with Yang. I also have a theory that his drinking is due to depression over Summer's death.
