From the screenshot below, you can see all boy's names that start with E. Although Edward was very popular in the late 1800s, Eric started to dominate in the 1950s, and Elijah, Evan, and Ethan (our son's name, ranked #3 in 2007) have taken over since the 1990s.
My name hasn't fared so well (#6 in the 1880s, #262 in 2007). My wife's name went from a high of #13 in the 1970s, but it's since dropped to #105.
The creator of NameVoyager, Martin Wattenberg, writes about it in a white paper entitled Baby Names, Visualization, and Social Data Analysis.
