Yorkshire County Cricket Club [SEP] Origin of club
The first club President was former player Thomas Barker, who had become Mayor of Sheffield, although he probably never attended any meetings. Michael Ellison was the first club Treasurer and at some point early in Yorkshire's history, he assumed the Presidency. Most official accounts record Ellison as Yorkshire's first President. Joseph ("J. B.") Wostinholm became the first of four long-serving club Secretaries in 1864. The first team captain was Roger Iddison, a professional cricketer.
