Who Do You Think You Are?

Laurence Llewelyn-Bowen (5x8)

:

"Most people assume that I'm from a long line of gothic, castle-dwelling Welsh gentry", says Laurence, "but I don't think I am". However, an old family letter hints that some of these assumptions may in fact be correct. Following a tantalising clue left by great-aunt Kitty, Laurence sets out to investigate. Is there a long lost family estate and fortune somewhere in Somerset? Could Laurence really be a member of the landed gentry?
