This example serves to point out that naming children after particular events that occur around the time of their birth or conception is a worldwide phenomenon. There are several examples of Hollywood celebrities who have claimed to have named their children after the places they were conceived. When the sociologist CatherineCameron did interviews of young parents in California several decades ago, she found that the largest number of girls named April were born in January (do the math!). And of course the names Noel and Natalie go back to naming children after being born at Christmas, Pascal goes back to naming children after being born at Easter, and Tiffany goes back to naming children after being born at Epiphany. The use of Liberty as a girls' name is today general in the USA, but if you look at the SSA year by year top 1000 lists you will see that there were two years before 2001 when Liberty made the list: 1918, the year when the USA's involvement in World War I was supposed to be "making the world safe for democracy", and 1976, the year the USA celebrated the Bicentennial of the American Revolution. I had a student a few years ago who told me her older sister was named Liberty because she was born in 1976.
