Bellatrix Black and Rodolphus Lestrange <<< You know what's remarkable about the HP series? Every single married couple in the books have an incredibly strong relationship. They may be assholes or straight up evil, but just like the good guys, they love their spouse within an inch of their life and would sacrifice anything for them. In fact, there are only two married couples that I know of that don't have that sort of relationship - Snape's and Tom Riddle' parents.
I kind of disagree with this I mean think of all the amazing muggleborns out there *cough cough* Lily Potter*cough* Hermione Granger *Cough cough* I therefore claim this as CONTROVERSIAL
Narcissa is my favorite character, she was never an official Death Eater and didn't have the Dark Mark either. She would do ANYTHING and I mean ANY EFFING THING for her family and never let anyone, not even Bellatrix, insult her Husband Lucius and Draco
Bellatrix Lestrange from the Harry Potter series is this to Voldemort without technically being his wife. She actually has a husband named Rodolphus but is more infatuated with Voldy; Word of God has it that Bellatrix's and Rodolphus's marriage is loveless. Rodolphus is mentioned only briefly in the books and not included at all in the movies
