Who Do You Think You Are?

It's now the ninth series of 'Who Do You Think You Are', and ten more celebrities are delving in to their own family history.

Each week we will be adding a blog about the celebrity featured, with details about their ancestors.

Read on for more information about the celebrities featured in this series...

Samantha Womack is an actress, most recently well known for her role as Ronnie Branning in EastEnders. She was born in 1972 in Brighton, where she was brought up by her mother after her father left home when she just 6 years old.

More recently, her estranged father committed suicide which prompted Samantha to start looking in to her family history.

Gregg Wallace is a former greengrocer. He now runs a successful restaurant and refers to himself as "the fat, bald bloke on Masterchef who likes pudding". He was born in Peckham, south east London in 1964.

His parents divorced when he was a teenager and he went on to discover his mother's long term lover was actually his father. His story looks like it is going to be really interesting.

Alex Kingston was born in Epsom in 1963. She is an actress and has starred in the American series ER and Dr Who. Her father is a butcher and her mother is German.

Will her story take her across to the continent?

Singer and political activist Annie Lennox was born on Christmas Day in 1954 in Aberdeen. She was brought up in a two roomed tenement apartment with communal laundry facilities. Her father worked in a local shipyard. Life must have been tough for them.

Will she find life was tough for her ancestors too?

Hugh Dennis is an actor, a writer and a comedian who was born in 1962. His father was a parish vicar, who later became the bishop of Knaresborough.

We know that his story includes two very different experiences of World War 1, so it is bound to be a fascinating one.

Better known as Ken Barlow in Coronation Street, William Roache was born in 1932 in Ilkeston, Derbyshire.

Will the lives of his ancestors mirror those of his alter ego Ken? Will they have northern working class roots? We do know his grandfather was a freemason devoted to the working of Rudolf Steiner, so we look forward to finding out more.

Celia Imrie is a successful actress who was born in 1952 in Guildford Surrey. In the past she has said that she has already found out about her mother's side, tracing the family back to God!

Her father's side of the family were from Glasgow and her surname is ancient Scottish, so we wonder what she'll discover about this side of the family.

The actor Patrick Stewart was born in 1940 in Dewsbury in West Yorkshire. His father, Alfred, was a regimental Sergeant Major who served with the Kings Own Yorkshire Light Infantry in World War 2.

We look forward to hearing more about his experiences.

John Bishop is a comedian from Liverpool. He also does a lot of work for charity. Earlier this year he completed a 290 mile triathlon for Sport Relief, going from Paris to London in just 5 days.

John's own family history apparently includes some colourful characters including Crimean War fighters.

Footballer John Barnes has played for several English teams during his 20 year career. He also has 79 caps for England. However, his roots are in Jamaica where his story on Who Do You Think You Are takes us.

John learns that his family were involved in the country's fight for independence so this story should be quite intriguing.
