Why did they name you Bellatrix Lestrange?

My dad was a Death Eater then he came back. Then my mom was. Then both they were both Death Eaters! So they were glad that I got an envelope from Hogwarts so they dont have to worry about watching me

Yeah their deatheaters they also put my name as bellatrix Lestrange but I changed it to Miratrix Blood

My parents are Death Eaters...Well my mother is..So I live with my dad. -Oh how rude am I! I'm Lestrange, Akiko Lestrange

So are your parents Death Eaters?
