So far we have been able to track down two Halstead's who have taken part in the Olympic Games over the years
In recent time Laurence Halsted has fenced for the British fencing team and competed in both London (2012) and Rio (2016)
In older time the only one that I can find is Nellie Halstead
She was born in 1910, the daughter of CHarles HALSTED and Florence Ann BURSTON and lived to the age of 81. She was at one time known as "Britain's greatest woman athlete"
She competed in the 1932 games in Los Angeles and was part of the bronze medal winning team in the 4x100 metres relay.
Rather than copy what other have written about her it is easier to provide the links to their websites

If you any more then please let me know and I will add them to this page
