|Character Profile||List of appearances|
Marnie arrived in Hollyoaks in February 2016 - a month after her eldest son James - in search of her ex-husband Mac. As Mac had received large amounts of money in their divorce, Marnie threatened to take their daughter Ellie as she left the village unless Mac paid her a large sum of money. Mac agreed and paid money, but Marnie's second-eldest son Nathan revealed that Marnie and Mac's adoptive son was actually conceived during an affair between Mac and Cindy Cunningham in 2001. Marnie then decided to reveal the news publicly in The Dog in the Pond.
Setting her sights on The Hutch, Marnie stole Diane Hutchinson's computer and realised that the restaurant was losing money. Marnie attempted to convince owners Diane and Tony Hutchinson to sell the business to her, but they refused. Marnie was later informed by Cindy that Alfie had been diagnosed with cancer, having beaten cancer already in his childhood. Marnie supported the family and Cindy through the battle, as well as Nathan when his fiancée Rachel Hardy was killed in a car explosion.
Marnie was left devastated by Rachel's death and met Freddie Roscoe at The Loft where they ended up having a one night stand. She later learned that Freddie was dating Ellie and attempted to force Freddie to end their relationship, but Freddie blackmailed Marnie with a photograph of himself and Marnie kissing.

After convincing Myra McQueen to demand £8,000 from the Hutchinsons for a jeck injury sustained at The Hutch, Diane and Tony were forced to sell the business to James and Marnie. In June 2016, The Hutch was re-branded and opened as Nightingale's - to Ellie's dismay as Marnie had told her that she planned to turn the restaurant into a cosmetics store for Ellie to run. In November 2016, Marnie was scammed by supposed-property developer Jude Cunningham, and called her mother Tabby Maxwell-Brown to ask to borrow £60,000. Tabby attempted to convince Marnie to leave Mac, but Marnie told her that she was still in love with him, and Tabby left.
With her relationship with Ellie struggling, Marnie lied that she had been diagnosed with a brain tumour as to not lose Ellie. Mac shortly discovered the truth and threatened to tell Ellie, but decided to tell the family that Marnie had been misdiagnosed following Nathan's death. After discovering that Mac had pushed Nathan to his death and had also caused the explosion at Hollyoaks High School that killed Neeta Kaur, Marnie and James decided to take Mac down for good.
