Unknown Voyages To The 'New Found Land'

Was William Weston the first Englishman to sail to the new world? From the Daily Mail:

Dr Evan Jones, a historian at Bristol University, has discovered that a Bristol merchant, William Weston, undertook a voyage to the 'New Found Land' in 1499 just two years after Venetian explorer John Cabot 'discovered' North America. The main evidence for the voyage comes from a personal letter written by King Henry VII to his Lord Chancellor on March 12 1499. The letter was found 30 years ago and mis-catalogued among a bundle of Chancery files in what is now The National Archives. The research will be published this week in the academic journal Historical Research.
