Troubadour
She had kinda a lonely childhood. Her and her mom were drifters and outcast. No siblings
I'm sorry to say this but that's a cop out. Who decided they were outcasts? How did they find out? Were they called derogatory names every where they went? What were those names?
Humans are social animals and seek each other out, especially children. Saying they were loners does not mean they didn't have any relationships at all. How did they interact with the people they met? Were there some who didn't care they were outcasts? Did they met other outcasts?
I'm not saying you should develop a comprehensive biography of your characters. But you should have at least a rough idea of what their past was like.
