Maraudettes

What if the Marauders, Lily and Snape all had siblings, who attended Hogwarts. Meet Jade Potter, Sarah Black, the twins, Rosa and Rebecca Lupin, Sevra Snape and Leon O"Ryan Evans as they make mischief, get into trouble and annoy their siblings. (Peter will be in this story but he doesn't get a sibling cause I don't like him very much.) Sorry ahead of time for mistakes!
