Eloise Mumford debuted on Hallmark as Maggie Conway in the 2012 film "Christmas with Holly," based on the 2010 book "Christmas Eve at Friday Harbor" by Lisa Kleypas. Mumford and Sean Faris led the film's ensemble cast, which included Alex Paxton-Beesley, Catherine Bérubé, Josie and Lucy Gallina, Daniel Eric Gold, and Dana Watkins.
The movie tells the tale of a young girl who loses her mother and has to live with her three uncles. The child stopped talking after her mother's death, however, things take a turn for the better when her uncle Mark (Faris) meets recently-single toy store owner Maggie Conway (Mumford). The film is a heartwarming exploration of new love, the importance of family, and the holiday spirit.
This project paved the way for a great working relationship between Mumford and the network, and she has since starred in six more Hallmark films.
