Fallin, of Norwegian origin, is an uncommon given name that translates to 'descending' or 'falling'. It gained minor popularity during the mid-20th century and has since maintained a steady, albeit low, presence in the U.S. and some Scandinavian countries.
"Annual birth totals for the name Fallin are notably consistent between 1982 and 1987, with five births each year, resulting in a total of fifteen babies named Fallin during this period."
