I believe so. Her back story is not yet been shown. But chances are she was a slave for a while. Edinmire, the human town where she, and maeve reside, and owns a tavern, outlawed, and made slavery in that town illegal
So I believe once she was free, and got used to being free, she bought a tavern, and runs it with her daughter
What happened to the father, I have no idea
He could've ran off, in a war, killed, or what probably happened, got captured and enslaved
