I found it very irritating when he kept on saying "famous ancestor" when the unsuspecting person wasn't descended from the famous person or even on the same branch of the tree.
The florence Nightingale connection was tortuous to say the least and when they asked a woman what it felt like to be descended from Queen Victoria when the person was actually descended from an ancestor at the time of Edward 111 well I gave myself a sore throat shrieking NO NO! at the screen. I have written to the UKHistory channel and given them a telling off too
