Every Olympic Games produces an Official Report. Usually all participants are listed. You might want to check the British Olympic Association web page - they should have a reference section where you can look up team members. I feel the best source is the LA84 Foundation website (http://www.la84.org/
). They have the best research center for sports in the world and you have easy access to many journals and documents - including every Olympic Official Report since the Games began in 1896 - all view-able online. You might also want to check the International Olympic Committee website (www.olympic.org
I hope this helps.
