Most enduring/classic names of all time

What do you think some the most classic girls and boys names are? In one baby book it said that [name_m]John[/name_m] was in of the most popular names in the world but I wonder how accurate that statement is.
In my mind:

1880-1920 [name_f]Mary[/name_f] and [name_m]John[/name_m]

1930- [name_f]Mary[/name_f] and [name_m]Robert[/name_m]

1940- [name_f]Mary[/name_f] and [name_u]James[/name_u]

1950: [name_f]Linda[/name_f] and [name_u]James[/name_u]

1960: [name_f]Mary[/name_f] and [name_m]David[/name_m]

1970-'80s- [name_f]Jennifer[/name_f] and [name_u]Michael[/name_u]

1990: [name_f]Jessica[/name_f] and [name_u]Michael[/name_u]

2000- [name_f]Emily[/name_f] and [name_m]Jacob[/name_m]

2010- [name_f]Isabella[/name_f] and [name_m]Jacob[/name_m]

2020- [name_f]Emma[/name_f] and [name_m]Liam[/name_m]

Depends on what country you mean. The most enduring names in [name_f]Italy[/name_f] are going to be vastly different from those in the United States, for example. I’d say that [name_m]John[/name_m] is one of the most common names in the English-speaking world but probably not in the entire world.
