Can you just imagine if the present day family was somehow really descended from Quentin and Jenny!!
Hmmm - here's a theory that's even possible: maybe Quentin's son never did die - Magda actually whisked him away to be raised by the gypsies, he married a gypsy girl, but then the truth was discovered and his children were passed off as Jamison's. However, Liz had faint memories of living in the caravans but just passed them off as dreams until she finally had to face the truth and admitted it to Stokes.
Weirder things happened at Collinwood!!
