Last Names Commonly Used as First Names

Ever notice that you sometimes can't tell if someone's names it their first or last? These are the ones that should be the most confusing.

The Trend

in 1937
in 2016

To investigate this naming trend, we only looked at names with a decent amount of ambiguity: the first name couldn't outnumber the last name by more than 10 to 1 and vice versa. At the peak in the 1940s, these names accounted for 40% of babies born in the U.S. As you can see from the graph, the usage of these names is declining. During the 90s, the trend began to decline more rapidly as unique names and unisex names became more popular.

The List

To make it to the top of the list, a name has to have a cominbation of ambiguity and popularity. Some names were incredibly popular - like Thomas 2.3m. Others like Wade 68k are split almost 50/50 with their usage between first and last names. Some of the most interesting names that made the list are unisex names like Kelly 552k or Casey 185k that are difficult to distinguish if they are a boy, girl, or last name.
