Mary Elizabeth McGlynn (born October 16, 1966), also known as Melissa Williamson, is an American voice actress, ADR director, writer, and singer best known for her extensive English-language dubbing of various anime, her singing in the Silent Hill series, and Dance Dance Revolution EXTREME.
McGlynn has also had several movie roles throughout her career and is currently married to Daran Norris. McGlynn was formerly a counselor at the Interlochen Arts Camp in Intelochen, Michigan.
Silent Hill series
McGlynn has provided vocals for the soundtrack of every game in the Silent Hill series since Silent Hill 3. McGlynn has also provided vocals for some tracks in the 2006 movie adaptation of Silent Hill. McGlynn has frequently worked with Akira Yamaoka and Joe Romersa. Her favorite Silent Hill song is Room of Angel.
Following Yamaoka's departure from Konami, McGlynn confirmed that she would not be returning to make music for the soundtrack in Silent Hill: Downpour. She will instead work with Yamaoka on other projects, like the third person shooter game Shadows of the Damned; however, it was later announced that McGlynn would indeed work with Downpour's composer Daniel Licht on the soundtrack of the game. Eventually, she provided some background vocals on the tracks Intro Perp Walk and Bus to Nowhere.
In 2011, Mary was asked by Konami to direct the voice acting for Silent Hill HD Collection due to James's original voice actor requesting residuals for ports and re-releases of Silent Hill 2.  For the re-dub, Mary approached Troy Baker to voice James. She voiced the characters Mary and Maria, as well.
