Conleth Hill and Benny Hill have very little to do with each other, and are certainly not related.
For starters, Conleth Hill's family has its roots firmly in Northern Ireland, while Benny Hill's family come from Southampton, and goes back generations and generations.
They also had very different paths to fame.
Benny Hill (who's real name was Alfred - he changed his name to Benny after the comedian Jack Benny) was once an employee of Woolworths, and has been everything from a milkman to a bridge operator.
Conleth Hill on the other hand is a trained stage and screen actor who has taken part in several high profile modern TV and film roles, such as a place on the cast of hit HBO series Game of Thrones.
