Who Do You Think You Are? (BBC1, 9pm)

FOR a decade this always-watchable series has changed the face of genealogy around the world with countries including Poland, Canada, Australia, America and Germany all signing up to the format.

Bill Oddie, Amanda Redman and Sue Johnston were among the celebs to take part in that first series, and it became the channel's highest- rating programme of the year. Memorable moments have included Jeremy Paxman's now famous tears as he learned all about the hardship endured by his great-grandparents; Patsy Kensit discovering her grandfather was a prolific criminal, and Alistair McGowan's shock at finding out he wasn't who he thought he was.

This time, cover your eardrums for the bombastic but brilliant Brian Blessed plus Tamzin Outhwaite and Billy Connolly. The opener looks appealing with actress Julie Walters determined tgo fight back the tears as the latest brave soul to delve deep into her family's history.

She turns 65 next year having shot to fame in 1983 playing the title role in Educating Rita, for which she won a Bafta and Golden Globe Award. Tonight we find Walters discussing her love of the country (she lives on an organic farm with husband Grant Roffey). She learns about her roots, which take her back to County Mayo, Western Ireland, where her great-grandfather Anthony Clarke was one of the first members of the Land League, an organisation formed in 1879 which campaigned for impoverished tenant father to have the right own their land.

Soon, she’s faced with tales of starvation, poverty, crop failures, evictions and trumped-up police charges. Who needs The Village?

Kids with Cameras: Diary of a Children's Ward (ITV, 9pm)

AT the Great North Hospital in Newcastle (which is part of the famous Newcastle RVI site) more than 100 youngsters have turned the cameras on themselves and record their experiences of the hospital and let us into the daily routines of their lives – all for this new heart-warming three-part series. First up, we meet eight-year-old Isaac, who's spent the last six weeks in hospital after suffering a bout of eczema caused by a severe reaction to food. The youngster has to be bandaged 24 hours a day to control the condition, and he talks of his treatment in his video diary, as doctors try to find a food type that is safe for him to eat.

Meanwhile, six-year-old Samuel has anaemia and has been in and out of the hospital from being three months old. We also meet Jocelyn, who had an eye infection that spread to her brain, asthmatic Tyrone and nine-year-old Amelia who has juvenile arthritis.

First Time Farmers (Channel 4, 10pm)

THIS fascinating series has been brought back for a second run, and first up, we're meeting three young farmers from Herefordshire. Dairy farmer and student Kate hardly looks the part, but she loves cows and so she manages to fit in milking duties in between the partying and mixing with boys. She also helps to deliver calves, and even rears some in her back garden for a uni project...

We're reintroduced to Robbie from the first series. He's now selling rare-breed pork from his mum's farm. In an attempt to drum up more business, he heads off to the country fair and competes in a cookery demonstration against his dairy farmer friend James.
