Mire and her identical twin, Sohur, emigrated to Sweden where an older sister lived and received asylum. The twins later moved to the United Kingdom to study.

Birmingham played in two Inter-Cities Fairs Cup finals, in 1960, as the first English club side to reach a major European final, and again the following year. They won the League Cup in 1963 and again in 2011.
