About the name Lex
Lex belongs to the English & American tradition. Its roots are documented, even though its precise meaning is not recorded in the standard references — an honest gap we prefer to a confident guess.
In the United States, Lex first appears in Social Security records in 1892. It climbed to its best-ever rank of #913 in 1956, and in 2024 65 babies received the name — 3,934 in total since 1880. Those are the official counts, not estimates.
