Doesn't always work, my son's name (Jackson) was at number 100 the year I was pregnant with him. I like the name and thought it would not become too popular. I was wrong! I believe last year Jackson was in the 30s for popularity!
Most of the Jacksons I know or hear around town are younger then my Jackson.
Although I still love the name Jackson, I wish it was die down in popularity!
Same with Cameron. It was pretty rare now, not so much. Also Kaylee, but she goes by Kate at school and she is the only one with that name.
