Mary kept its spot throughout the next decade, joined by "Robert."
At the end of the 1940s, Mary gave way to "Linda."
But in the 1950s, back to Mary — and "Michael."
Michael held out for most of the 1970s.
And all through the 1980s, along with "Jennifer."
Things stayed the same until 1985, when "Jessica" took over.
In the 1990s, there started to be some variations in girls' names — but not as much among boys.
In the 2000s, "Jacob" led the pack for 10 straight years.
Until Jacob gave way to "Noah" in 2013, and "Sophia" and "Emma" took over.
