Rhettlee is an uncommon, unique given name of probable American origin, first noted in the late 20th century. It consists of two parts: 'Rhett', a diminutive of the English name Rhett, which itself has uncertain origins but may be derived from the German word 'Rett' meaning 'to save', and 'lee', an English name element that can denote a calm or peaceful place.
"Rhettlee saw a slight uptick in popularity between 2021 and 2022, with 6 births each year, but has otherwise maintained a steady birth rate of around 5 per year since 2018."
