Sweetheart
DeMolay Chapters may elect a "Chapter Sweetheart" to serve as the female representative of the Chapter, although she is not an initiated member of DeMolay. Her duties may include attending Chapter functions and acting as an ambassador of DeMolay. The "Sweetheart" must meet the age requirements of a particular jurisdiction or Chapter (often 14 to 21.) She may be a member of a neighboring Job's Daughters Bethel, Rainbow Assembly, or Triangle, but that is not a set requirement in most Jurisdictions.

Chapter Princess
A Chapter may also elect a Chapter Princess. The program generally uses the same requirements as set forth for the Sweetheart. Her duties generally include attending Chapter functions and acting as an ambassador of DeMolay while assisting the Sweetheart in her duties.

Chapter Duchess

A Chapter may also elect two Chapter Duchesses. The program generally uses the same requirements set forth for the Sweetheart. Her duties generally include attending Chapter functions and acting as an ambassador of DeMolay while assisting both the Sweetheart and Princess in their duties.

Chapter Little Sis
A Chapter may also elect other females, who may or may not be a member of Job's Daughters International or International Order of Rainbow for Girls, to be a Little Sis. She is usually 14–16 years old. She generally assists both the Princess and the Sweetheart in their duties.https://en.wikipedia.org/wiki/DeMolay_International
