The most frequent roles for guest actors in "Only Fools and Horses" were as Del or Rodney's once-seen girlfriends, barmaids at the "Nag's Head", or individuals the Trotters were doing business with. Del and Rodney's deceased mother, Joan, though never seen, cropped up in Del's embellished accounts of her final words or in his attempts to emotionally blackmail Rodney. Her grave – a flamboyant monument – was seen occasionally. Their absent father, Reg, appeared once in "Thicker Than Water" (played by Peter Woodthorpe), before leaving under a cloud, never to be seen again. Other members of the Trotter family were rarely sighted, the exceptions being cousins Stan (Mike Kemp) and Jean (Maureen Sweeney), who attended Grandad's funeral. In "The Second Time Around", the woman they believed to be Auntie Rose (Beryl Cooke) turned out to be no relation at all but the woman who'd moved into Rose's house some years earlier. After Rodney met Cassandra, her parents Alan (Denis Lill) and Pam (Wanda Ventham) became recurring characters. Raquel's parents, James and Audrey (Michael Jayston and Ann Lynn), appeared in "Time On Our Hands", and it was James who discovered the antique watch which made the Trotters millionaires.
