Needs help with a baby girl name

Hi there, I am currently pregnant with baby number 4! We are having a girl. I am having a hard time finding a name I love as much as my other 2 girls. My oldest is Scarlett Rose, my son Is Colton Allen (my husband picked it) and my youngest is Isabella Grace. So my dilemma is, I love somewhat different names and my husband likes more normal names. I do like Violet, but we have a Scarlett and I like Stella but is that to close to Isabella? then I like Sadie but seems a little like a dogs name. Im opened to anything at this point.
