Gabrielle Dowling (born 13th December 2006 in Huddersfield, West Yorkshire) is an English actress who has portrayed Viv and Bob Hope's daughter Cathy Hope in Emmerdale since February 2007. Her twin brother Sebastian Dowling played Cathy's onscreen twin brother Heath.
The Dowling twins were supposed to play Cathy and Heath from the characters' onscreen birth on 9th February 2007, however Sebastian had to stay in hospital for an additional week which meant Ella Whitehouse Downes and Lilith Kitching appeared as Cathy and Heath for the characters' first few appearances before the Dowling twins took over the roles from the episode broadcast on 14th February onward.
