Baby girl name

I have a little boy named Callum and our last name starts with a C. I'm having a little girl in December and if I could name her anything I would name her Clover, but my family is shooting it down. So far we have compromised on Clara which I also love, but I'm not 100% of the way there yet. I'm also a little worried about the matchy-matchiness of the names Callum and Clara, but to be honest...I just don't have many other names I like (that haven't been used recently by close friends or family). Trying to feel confident in a decision.
