Yvonne’s mother, Ruth, was the only surviving member of her German Jewish family – the rest had died during the holocaust. Ruth moved to Israel when Ken and Yvonne got married in 1966. Ruth and husband Aron’s new life awoke a Zionist interest in Ken. Aron was a member of Parents Circle, established by Israeli and Palestinian parents who had lost a child in the conflict. Inspired by Aron and a visit to Israel, Ken and Yvonne established the British branch of Windows for Peace in 2003. Their charity works with Israeli and Palestinian teenagers to build bridges between the two groups.
