About the name Arch
Arch 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, Arch first appears in Social Security records in 1880. It climbed to its best-ever rank of #199 in 1880, and in 2024 37 babies received the name — 2,526 in total since 1880. Those are the official counts, not estimates.
