So she is related to Sven? But isn't Ariel's father Sven? ....what?

Claire is a copy of Sven- she's from a universe where basically the only thing different from Sven's native universe is the gender of everyone. As far as Sven's daughter is concerned, you're thinking of Violet. Sven and Ariel have had three children: Aaron, Isaac, and Violet. Aaron is dead.
