There are some new faces heading to Hope Valley!

With the arrival of the upcoming holiday special When Calls the Heart: The Greatest Christmas Blessing, the long-running Hallmark channel series is welcoming some new members to the cast!

In the hotly anticipated special episode, airing Christmas Day, the idyllic Canadian town of Hope Valley gets a visit from a group of adorable orphans and their adult caretakers, who are stranded in the town amid their perilous journey to a new orphanage.

Newcomer Jocelyn Hudon has been cast as Grace, one of the caretakers of the traveling orphans.

The 24-year-old actress comes to When Calls the Heart following recurring roles on a number of TV dramas, including Ice, The Strain, and 21 Thunder. However, she's certainly no stranger to family holiday fare, with roles in Hallmark's The Christmas Cure and the made-for-TV movie Christmas Wedding Planner, released last December.

Fans may have seen Kohan in her role on one of several dramas recently, including a recurring role on Ransom, and guest spots on Star Trek: Discovery, In Contempt and The Murdoch Mysteries.
