My DD1 has a top 10 name. It was a shock to me when naming my child that DH didn't like any of the names I had always had in mind and I didn't like any of the names he had in mind. I forgot that it wasn't all MY choice So, DD1's name was the only name we liked on at the time.
She does have another of the same name in her class at school. But then again there are 2 Harriets and that's far from a top 10 name.
For DD2 I liked Annabel and for awhile wished we had called DD1 that name as it is less popular. If we had called her Annabel, she would have been one of two Annabels in the class!
We didn't name DD2 Annabel But her name, which is ranked between 40 and 50, is heard more frequently in our area than DD1s. You can't win. It is best to go with the name you and your DP like the most.
