Hooray for the Obama family!
Americans love a naming trend and they love to show their patriotism. Thus, a new president's name often gets a bump in the Social Security charts after he is elected. For example, "Grover" was #410 in 1880, but jumped to #20 during the election of 1884 and stayed in the top 100 for a decade. "Woodrow" was obscure (#1049) in 1900, but hit #46 in 1912. "Franklin" hovered between #119 and #187 for the first 32 years of the 20th century, but rocketed up to #33 in 1933. Obviously, it's difficult to see any appreciable bumps after the election of a William or a John, but I think we will probably see "Barack" break into the top 1000 soon enough.
In honor of our new president, I took a look through the census records and found lots of little Americans who have been named for our presidents. Unsurprisingly, they often travel in sets.
*After Hoover, it gets a little tricky because the post-1930 census records are not available yet. Ancestry makes some state birth records available, so I have used these, along with some marriage records, to find presidential names after Hoover. Unfortunately, the lack of census records makes it difficult to find matched sets of siblings.
