I was just talking to DD and telling her we had to run out to someone's house. When she asked who, I told her it was Kaden's house (which happens to be her step brother's name and also a friend of hers in her Kindergarten, and also my cousin's name, and also the name of one of our babysitters + we know numerous others). This was very confusing to her and she had no idea where we were going until we got there because she hasn't grasped the concept of last names yet.
I personally prefer unique names or names that aren't trendy or popular for their time. My name was popular back in the 50's and in my entire life, I've only met one person with my name that wasn't 30 years older than me. In a way I liked that. Common enough that people don't say "What??" when I tell them my name, but unique enough that I don't have to worry about hearing my name in public and wondering if it's me they are talking to.
I don't know what they have in the states, but here in Alberta, I can go to the government of Alberta website and look up the birth names for the past couple years just in our province. It tells the most popular names and then also shows a list of ALL the names of babies born in that year in our province and how many kids with that particular name/spelling their were. I like to look at it because some names that I've only just heard that I think are cute turn out to be super popular. I have yet to see my DS's name make the list. DD1 turns out her name became popular that year. I had never heard it before - she doesn't have any friends with the same name but we have heard of people with children with the same name. DD2 has a name that HERE is not popular but in other parts of the world it is. In fact a cute thing is, I bought her a coloring book the other day that had a story line in it and one of the Princesses had her name (spelled differently) and we thought that was pretty cool.
All that said...I think if you really like the name you should go for it anyway...unless you already know 5 little boys in town with the same name.
