Is Mary my cousin?

So last week Elisabeth and I were driving in my car and she asked "Mom is Mary my cousin?"
Of course I was confused at first and said "no. Mary is grandmas first name." Then she said "well in the Bible it says that Mary went to talk to her cousin Elizabeth. " It was then clear to me what she was talking about. I reminder her that we know lots of people with the same names and that she just has the same name as Mary's cousin.
