The Black family is one of the most prestigious pureblood families there is in the wizarding world.
Almost everyone knew about the Black family and what they had for breakfast every morning.
The amount of coverage that family received was ridiculous.
So when it came to light that one of the many Black daughters had fallen pregnant with a muggle's child, it was the first page of the Daily Prophet.

Many of the scary twenty-eight families had expressed their condolences to Druella and Cygnus Black once they saw the news, losing two daughters to the others had to just be traumatizing.
The two parents had shunned away yet another daughter, burning off her delicately painted face on their family tree.
From that moment forth, no one in the Black family knew of an Esther Black.

When Elara Black had stepped onto Hogwarts school groups, she becameHogwarts school groups, she became an immediate target to the violent nature of purists and fearful students.
Her whole life consisted of her having to defend her last name and she was tired of it.
Of having someone pull her hair in the hallways.
Of a Slytherin purposely pushing her out of the way and onto the ground. Of others whispering when she walked by.
Elara just wanted to breathe and forget that she was a Black.
And that only happened when she was around a certain redheaded Weasley.
