"You are my face; you are me"

With my theme being the relationship between a mother and daughter- I thought naming my book would not be that difficult to name. I have discovered that the line of being very specific and to broad is hard to get by. My titles have either been to broad so the reader doesn't get a sense of intrigue, they would already know that the book is about a mother and daughter. Then I come up with titles that represent a relationship, but what kind of relationship? I wonder if it is better to be more broad, then as the reader goes through the book by the end they know what the relationship is portraying. Choices, choices, decisions, decisions.... 
My ideas so far: 
A Connection
Between Me and You*
Our Link
First Born
My Mirror Image*
The Two of Us: Mother and Daughter
My Mother: Mia Madre 
Motherhood
You are Me*
Side by Side
It Takes Two 
One and Only
