Combination of Tracy and Rochelle
Trachelle is a modern American blend, likely created by combining the prefix of Tracy (meaning 'of Thracia' or 'domain of Thracius') with the suffix of Rochelle (meaning 'little rock'). It emerged in the mid-20th century as part of a trend of creating unique feminine names using the popular '-elle' suffix.
