what do you ladies think of these names?

Dacia

So me and My SO have been debating and he wants these crazy off the wall names. I let him and my mother name my last child so I feel like I want to name this one. Still do not know the gender but I'm almost positive I have chosen the names I like. If we have a boy I was thinking Mason Elijah Harris and for a girl Emma Rose Harris. Emma was the name my. oldest daughter chose and I love that name for a girl. What do you think. If any other suggestions I'm open to anything.
