This is taken from the Dubai Manx website run by WMA member Gil Costain-Salway:
The WORLD MANX ASSOCIATION was founded in 1911 by the then Chairman of the Castletown Brewery, Mr. Richard Cain, who was inspired by a remark made by the Manx national poet T.E. Brown about Manxmen returning from overseas. During a lecture Mr Brown said "We should welcome them back with a shake of the hand and a clap on the shoulder". Though not founded until after T E Brown's death, the occasion was well documented in a newspaper at the time, the ‘Mona's Herald’, which reported "a gathering of unique character at Rushen Abbey." The meeting was of a number of visiting Manx emigrants from as far away as North America, South Africa and Australia and it was Mr. Cain's idea to make it a formal occasion "whereby Manx colonials and their friends could extend to each other the hand of friendship".
