No president in American history has served as long as FDR, who served four terms. However, neither the length of his presidency nor his accomplishments during those 12 years can be blamed for the massive increase in babies named Franklin that began gracing America's maternity wards—the greatest spike in babies named Franklin occurred at the start of his presidency.

According to a Slate article based on US Census data, the number of babies named Franklin increased dramatically within the first two years of his election, with 5 times as many Franklins born on the day he was elected in 1932 as the previous week. Throughout his presidency, parents continued to name their children Franklin, though the name's popularity began to wane. However, as Slate points out, there was one day on the calendar that produced significantly more little Franklins than any other—January 30th, FDR's birthday.

The most famous person to bear the name of America's first president was given the name by himself, rather than by his parents. The legendary agricultural scientist and inventor George Washington Carver was born into slavery, and his surname, Carver, was derived from the plantation owner. After introducing himself as "Carver's George", he was advised to change his name to George Carver, and it is believed that he took "Washington" as his middle name as a young adult, long before his own name became synonymous with his revolutionary work in science and agriculture.

Of course, the name George, and its feminine variants such as Georgianna, have been consistently popular American names for centuries. Not to mention the numerous structures, monuments, and airports named after the first President of the United States.

Simply visit the "Babies Named After the President" exhibit on the John F. Kennedy Presidential Library and Museum's website to get a sense of how much JFK influenced Americans. Hundreds of handwritten letters, excited birth announcements, and deferential telegrams from excited new parents, some from as far away as Ghana, informing Kennedy that they were naming their newborns after he are on display. They convey a true, visceral sense of the love, hope, and honor bestowed upon JFK.

It's no coincidence that the name "John" peaked in popularity in the United States in 1964, with 82,541 boys given the name the year after his death. Since then, it has remained a popular name and honorific title.

"This machine kills fascists", legendary folk singer and political activist Woody Guthrie famously scribbled on his guitar. Guthrie, who was originally named Woodrow Wilson Guthrie after the 28th President of the United States, was one of many Americans whose names were a nod to the Democratic president.

Woodrow was an English name at first. Its popularity in America skyrocketed after Wilson became president: there were only 121 babies named Woodrow in 1911, the year before his election. When he was sworn in as President the following year, that number jumped to 1,843 boys (and 11 girls) named Woodrow.

Because of the religious significance of the name Abraham, it's impossible to say how many Abrahams was given the name in honor of Lincoln. However, unlike names like James, which have been shared by multiple presidents, there was only one president named Abraham, a fact that highlights Lincoln's enormous influence over the country and parents in particular.

According to the Huffington Post, the name Abraham has endured in the same way that Lincoln's legacy has: in 1900, it was the 195th most popular boy's name; more than a century later, in 2013, it was still ranked #183. And, perhaps more than any other president, Lincoln's name is associated with countless memorials, schools, museums, and other civic endeavors across the country.

If you only look at raw numbers, you might be surprised to see the name "Barack" on this list. However, naming trends have less to do with isolated numbers and more to do with their correlation to one another over time. In that case, Obama should be on this list, and possibly higher up.

Consider the fact that in 2006, when Barack Obama was just starting out as a US Senator, there were 0 babies named Barack. Only one year after announcing his candidacy for president, the US Census reports five newborns named Barack. In 2008, the year he was elected, Barack Obama had 52 children, which increased to 71 in 2009.

When you consider the uniqueness of the name and its statistically meteoric rise in just a few years, it's clear that Obama belongs in the ranks of Kennedy, Lincoln, and others whose names appeared on birth certificates as well as ballots.

You may not know anyone named Grover, but you'd be mistaken if you thought this 22nd (and 24th) president didn't influence parents across the country to name their children Grover at some point. For one thing, Grover wasn't even a first name until the president arrived. Actually, it wasn't even his first name! Stephen Cleveland was named by his parents after a popular minister named Stephen Glover. The future president adopted the first name Grover as a nickname, which became popular in America after he became president.

One notable example of how the name spread in American homes is Hall of Fame baseball player Grover Cleveland Alexander, who was born while the president was in office. Grover has been the name of numerous American politicians, as well as famous athletes, entertainers, and, of course, one notable blue puppet.

With a larger-than-life personality whose rugged mannerisms and love of the outdoors have all but cemented his legacy in both the political and environmental arenas, it's only natural that the 26th President, Theodore Teddy Roosevelt, should have a stuffed bear as his most famous namesake.

The Teddy Bear, of course. Inspired by a failed hunting trip during which the president failed to catch anything and refused to kill a bear that his handler had caught for him out of pity, the Teddy Bear first appeared in a Washington Post political cartoon depicting the failed hunting trip, and later, after the creator received permission from the president, like the teddy bear, the soft, stuffed bear that may be every American child's first best friend.

There have been six Presidents of the United States named James. Not to mention the other historical figures who bore the same name. As a result, determining which president James was named after, if any, is more difficult than with other names. That is, unless your name is James Garfield Davis, in which case the name was clearly chosen in honor of President James Garfield.

It isn't much known about James Garfield Davis. So, what is his significance? Because of his grandson, Jim Davis created a famous cat and named him after his grandfather, who was named after the president. That's right, think about the connections between the wise-cracking, lasagna-slurping striped cat and the esteemed 20th President of the United States the next time you read a Garfield strip.
