Known to millions as the lead judge on the BBC's Strictly Come Dancing, Len 'SEEEVAAAHN!' Goodman nearly became a welder until a friend told him to try out ballroom dancing because it is 'full of girls and virtually no boys'.

He also uncovers a connection to silk weaving and sets out to solve the mystery of an ancestor's descent into poverty. Len also follows the trail of his Polish great great grandfather, Joseph Sosnowski. He wants to know how Joseph ended up in Portsmouth in 1834. As Len follows in his great, great grandfather's footsteps, he discovers the dramatic part Joseph played in the struggle for Polish independence.
