Who was the first non-Yorkshire born cricketer to play for Yorkshire County Cricket Club?

Thomas Rawson Barker..

Barker was born in Bakewell, Derbyshire, England, and was a right-handed batsman and a left round-arm medium pace bowler. He appeared in what is regarded as the inaugural Yorkshire first-class match at the Hyde Park Ground in Sheffield in 1833 against Norfolk, although at this time Yorkshire was still the Sheffield Club. In doing so, he became the first non-Yorkshire born player to play first-class cricket for Yorkshire.

YCCC was founded in 1863, one of the primary rules of the club was, no one could play for Yorkshire who wasn't born in the county.
In 1992, the birth qualification rule was first modified to include those educated within the county, a dispensation that allowed Michael Vaughan to play; and was then abandoned altogether. Yorkshire's first overseas player that season was 19-year old Sachin Tendulkar.
