About the name Mathieu
Mathieu 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, Mathieu first appears in Social Security records in 1955. It climbed to its best-ever rank of #1470 in 1998, and in 2024 25 babies received the name — 2,397 in total since 1880. Those are the official counts, not estimates.
