Adrian Dunbar and Neil Morrissey will discover their ancestry in a new series of DNA Journey later this year.
The fourth series on the hit show will see four celebrity pairings unearth their past and make life-changing discoveries in South Africa, Ireland and Norwich and St Helens, in England.
Northern Ireland-born actor Adrian Dunbar, best known for playing Superintendent Ted Hastings in BBC police drama Line Of Duty and for starring in The Crying Game, and ex-Men Behaving Badly star Neil Morrissey, who has Irish ancestry, will go in search of their ancestors together.
The pair will uncover the truth behind their bloodlines using the show's DNA technology and genealogy expertise.
Other celebrities taking part in the show include Paddington actor Hugh Bonneville, who lives in West Sussex, best known for playing Robert Crawley, Earl of Grantham in the Downton Abbey films and ITV series.
He will be paired with Liverpool-born comedian John Bishop.
Croydon-born comedian Alex Brooker, a co-host on The Last Leg, and Merseyside-born comic Johnny Vegas, who also appeared as an actor in Benidorm, will also explore their ancestry together.
In the final pairing, Oti Mabuse and her older sister Motsi Mabuse, both known for Strictly Come Dancing, will uncover their family's history.
The two ballroom dancers, who are from South Africa, moved to Germany and appeared on the country’s version of Strictly Let’s Dance before joining the celebrity dancing series on the BBC.
Voltage TV executive producer Kathleen Larkin said: "This emotional series has some jaw-dropping revelations showing that some of our celebrity pairings are more connected to each other than they ever dreamed of."
DNA Journey returns on ITV1 and Virgin Media in 2023.
