From the experts:
Dapper-sounding choice with old American roots (Dabney Cosby was a 19th century Virginian architect who worked with Thomas Jefferson on some of that state's most iconic buildings). Dabney Montgomery was Martin Luther King Jr's bodyguard, giving this name yet more American history depth. Dab is a sweet nickname option for this name.
