You can predict how popular your dcs name will be in 25 years in magazine time.com/93911/baby-name-predictor/. My DSs name barely registers even though I would say its a classical name.
What I found more interesting was the article www.theguardian.com/lifeandstyle/shortcuts/2014/may/12/noah-wyle-flood-baby-most-popular-boys-name-us on why names become popular they used Noah as a case study. One of my favourite teachers growing up has my sons name, I am sure subconsciously I was inspired by him.
