From her trivia: "In the [Mabinogion], Branwen is the sister of the King of Britain. She is betrothed to the King of Ireland in order to bring peace between the kingdoms. However, her betrothal does not prevent war, instead bringing ruin to both islands.

So given the likely allusions of Tai and Qrow to Oz characters, Cowardly Lion as King of the Animals and the Scarecrow as the King of the Emerald City, this would mean that Raven, as Qrow's supposed sister, would have married Tai not for love but for obligation (not necessarily to prevent war). Perhaps Qrow is a Faunus and a former high-ranking member of the White Fang during its peaceful years and Rae's marriage to the Human Taiyang represented a step toward peaceful relationship between the two species. It would seem the "arrangement" was somehow not mutual. Perhaps Raven seduced Taiyang, or maybe Tai, being in love with her, asked Qrow's permission to marry her. Either way, it would seem that the siblings agreed it was for the good of their species that she marry Taiyang.

"The Raven" ties in by how Raven suddenly disappeared and left Tai distrought to the point he turned to Summer Rose for consolement. He probably received visits from her which he mistook for spectres. Maybe she only ever appeared hidden in shadow. Maybe the reason Taiyang recently sent that letter about having to head out is because Raven has actually recently confronted him and shown him he's not hallucinating. It's possible that Qrow has known her whereabouts all along but due to family loyalty, never mentioned it to anyone.
