UPDATE: Baby Names for Future Daughter

Katelynn • Married•Dog Mom•
Well ladies I have this problem with my family and the name I want to name my daughter if I ever have one and I need advice of what to do.  Well my real moms name is Christina  Marie and she died from Cystic  Fibrosis when I was one and a half years old. So ever since i was about 12 years old I have wanted to name my future daughter after her and my daughters name is going to be Christina Marie Rayne. Well I mentioned it to my father one day and he didn't like it. I asked him why and he goes because it's your mothers name and I don't like hearing it....
So ladies what do I do??? Please any positive advice would be nice.
Update: 
So my dad just called me and he said that it was fine and that he was overreacting. He actually really loves the name and wouldn't mind it at all. He was just shocked that I would ask his permission. Thank you ladies for the advice and I knew my dad would come around and tell me how he truly felt.
