In the series, Marilyn was portrayed by Beverley Owen and Pat Priest; this version being played by other actresses in later movies and sequels. Debbie Watson played the character in Munster, Go Home! and this version was continued by Jo McDonnell in The Munsters' Revenge and carried over into The Munsters Today, played by Mary Ellen Dunbar and Hilary Van Dyke.
In the 90s and the the 00s, the character was completely ret-conned by Christine Taylor in Here Come the Munsters; this version continued by Elaine Hendrix in The Munsters' Scary Little Christmas. In 2012, she was retconned once more by Charity Wakefield in 1313 Mockingbird Lane.
Marilyn Munster is the niece of Lily Munster and Herman Munster and the granddaughter of Grandpa. She is also the cousin of Eddie Munster, Herman and Lily's son. In one iteration, she is the daughter of Herman's sister who had married Norman Hyde.
Not much is known about Marilyn's life. Considering she is in college in the 60s, she was born sometime around 1945. As a infant, she was taken in and raised by her aunt and uncle under unknown circumstances. No mention is made of her parents whereabouts, but since dying means little to the family, it is possible they are deceased in a manner making it difficult to raise her. Since her last name is "Munster," Herman and Lily likely adopted her, but she still refers to them as "Uncle Herman" and "Aunt Lily."
Marilyn is a very kind and genial person, and she looks after both her cousin, Eddie and the family pet, Spot. She is very attractive (although homely by Munsters standards), and dates often, but very few of her dates ever enter the family home, and the few who do get scared and flee by the window. She attends Westbury College, once nearly losing her scholarship, but Herman had her tuition re-installed. She is very close to her Aunt Lily, the two of them frequently observing her uncle and grandfather getting into shenanigans.
- There seem to be three iterations of Marilyn in the multiple franchises:
- The original Beverley Owen/Pat Priest Marilyn (loosely followed by The Munsters Today, Munster, Go Home!, The Munsters Today and The Munsters' Revenge.)
- The 1990s version where she was rebooted as the daughter of Herman's sister and Mr. Hyde in Here Come the Munsters and The Munsters' Scary Little Christmas.
- The 2000 reboot Marilyn in Mockingbird Lane, each of whom have differing histories and family trees. No notes are mentioned as to how she is related the Herman Lily, but it is likely she is once again Lily's niece.
- Beverley Owen starred in the two pilots and the first 15 episodes of the series. Pat Piest played Marilyn Munster for the rest of the series.
