So, here’s the thing. British and American families have broadly similar tastes when it comes to naming their children, with a few exceptions. You don’t tend to get as many British kids called Mason or Harper, and there probably aren’t as many American kids answering to Alfie or Jessica.
Looking over the popularity charts for baby names in 2012 (I was bored, OK?), one change jumped out above all others. In 2011, Amelia was the 11th most popular name for girls, occupying broadly the same position it does in the US rankings.
In 2012, the same year Amy Pond left the Doctor to be with Rory in the past (and Karen Gillan and Arthur Darvill left Doctor Who), it jumped to the No.1 position. Coincidence? No of course not.*
