The widow of a Bicester father-of-three killed in a car crash last year is helping organise a fun day in his memory to raise money for the Oxford Children's Hospital.

Joanna Buddin, 29, of Mulberry Drive, Bicester, was five months' pregnant with her third child when her husband Adam, 30, died last October.

In February, Mrs Buddin gave birth to their first son, who she named Jaycob Adam after his late father.

Mr Buddin, who worked as a training instructor at the Campsfield House asylum detention centre, in Kidlington, died in October, when his Audi caught fire after colliding with a Honda on the B430, near Weston-on-the-Green.

Former soldier Mr Buddin, who had served in Bosnia, Cyprus and Germany, was on his way to work when the accident happened.

Mrs Buddin said her husband had doted on his two daughters, Kayleigh, three, and Ashley May, two, and was thrilled to be expecting his first son.

She added it was Adam's devotion to his children which had prompted her to raise funds for the hospital appeal in his memory.

Four months before Adam died, Ashley had to have surgery, because the soft spots on her skull, called fontanelles, were prematurely fused.

Ashley spent 10 days in the Leopold Ward of Oxford's Radcliffe Infirmary a ward which is due to move to the children's hospital.

Mrs Buddin said Ashley had since made a full recovery. She said: "She's absolutely fine, she's doing great. She's had her two-year check. She's a bubbly little girl, but she's still crying for her dad."

Mrs Buddin, a former Bicester Community College pupil, met her husband on a night out in Bicester nearly seven years ago. They married in St Edburg's Church in 2001.

She said: "He was a family man, hard working. He really was full of life, he was always a positive person, always there, and everybody's friend. He was just so loving. You can't believe it happens to such good people."

Mrs Buddin also hopes to buy a bench for St Edburg's churchyard in Adam's memory.

She added: "I have all my memories, but the children, when they're older, that's all they're going to have. Jaycob looks so much like his dad. We had a scan two weeks before the accident and he knew it was a little boy."

Mrs Buddin and Adam's former workmates have organised a fundraising Buddin Family Fun Day at Lower Heyford Football Club tomorrow.

The event, which starts at 1.30pm, includes a pig roast, barbecue, six-a-side football contest, owl display, raffle, tombola, licensed bar, bungee run, bouncy castle and stalls. A trophy in Adam's memory will be awarded to the winning football team and a plaque will be donated to Campsfield House as a lasting tribute to him.

The England v Paraguay World Cup football match will be shown on a television at the event.
