Brantly is a unisex given name of American origin, derived from the Old Norse personal name Brandr, which means "sword" or "firebrand". It gained prominence in the United States during the mid-20th century and has since been used consistently, though relatively uncommonly, for both boys and girls. The name Brantly is often associated with the American aviator Charles E. 'Brant' Brantly Jr., who was a pioneer in helicopter flight testing.
"The name Brantly was born to five babies in total between 2012 and now."
