2. Jacob
Meaning: "Supplanter"
Rank: 4 in 2015

Jacob has proven to be an incredibly popular name in recent years — perhaps too popular. This Old Testament name was the most popular name for boys from 1999 to 2012 (13 years!), and even now it still sits pretty in the top 10. Seems like lots of parents discovered they weren't as into Team Jacob as they once thought they were.
