Just leaving this here as a bookmark for the girl later.
“Girls’ names typically cycle in and out of fashion more quickly than boys’ names … However, there are some exceptions — most notably Anna, which is a remarkably well-enduring girl’s name. The name Anna steadily declined in popularity from 1900 to 1950; however, many of those older Annas are no longer with us, and the name has remained at reasonably steady levels of popularity since then. Thus, while a quarter of living Annas are younger than 14, another quarter are older than 62.”
