Her uncle
‘By Ford was born in Castleford, Yorkshire. He spent his early years living around the West Riding of Yorkshire, where his father, Sir Lawrence Byford, served as a policeman. Sir Lawrence went on to become Chief Constable of Lincolnshire, and later, Her Majesty's Chief Inspector of Constabulary. Mark was educated at Lincoln School which later became Lincoln Christ's Hospital Comprehensive School.[1]
He returned to West Yorkshire in 1976, studying law at the University of Leeds, where he was president of Devonshire Hall. Immediately on graduating he joined the BBC in 1979, aged 20, as a "temporary holiday relief assistant" working as a researcher over the summer holiday in his local (Look North) television newsroom in Leeds. After three months' vacation work, he joined the BBC full-time.’
Strike me as a family that have achieved what they have by hard work and intelligence, not inherited wealth.
