Is Olivia too common?

I know no one named Olivia, no kids or babies named Olivia, and am loving the name—mostly because it is the ONLY name my husband and I can agree on.

My sister says it’s too popular and it’s number one on the baby names of 2018 so far, so I’m completely torn!

Middle name will be Clare or Elaine- both family names.

He likes names like Jessica and Samantha, I loved Ava and Harlow.

Thoughts or suggestions PLEASE?
