Heather North, an actress best known for lending her voice to the character of Daphne Blake on "Scooby-Doo," died at 71, according to reports. North died Nov. 30 following a long battle with illness at her residence in Studio City, a neighborhood in Los Angeles, California.

Family friend Jodie Mann confirmed Tuesday to The Hollywood Reporter that North had suffered a "long illness." North's illness had not been confirmed at this time, however.

North first voiced Daphne in 1970 during the second season of "Scooby-Doo, Where Are You!" She portrayed the fictional character in the long-running animated series over the next 30-plus year. The actress even lent her voicing abilities to the franchise's subsequent straight-to-video movies.

Her final voicing credit for Daphne was in 2003's "Scooby-Doo and the Monster of Mexico."

While North is widely known for her work in "Scooby-Doo" franchise, she has accumulated acting credits within a variety of other projects. North starred alongside Kurt Russell in the 1971 Disney flick "The Barefoot Executive." She also had a recurring role on soap opera "Days of Our Lives," but also earned guest starring spots on a television series "The Fugitive" and "Green Acres," among others.

North was married to H. Wesley Kenney, an Emmy Award-winning producer and director, for more than 40 years. Kenney, who died in 2015, was best known for his work on soap operas "Days of Our Lives" and "The Young and the Restless."

A memorial service for North is expected to occur at 11:30 a.m. on Wednesday at the First Christian Church in Studio City.
