Parr was born at Radcliffe-on-Trent in 1826 and was already making runs for Notts as a teenager when Clarke's All-England Eleven was founded. He joined the eleven in 1847, in his second season of regular first-class cricket, and quickly established himself as the side's leading batsman. His signature shot was a powerful pull off the front foot to a tree at Trent Bridge that became known as 'Parr's tree' or 'the Lion's leg-tree' — Parr was nicknamed the Lion of the North. He was less elegant than Pilch and less spectacular than Mynn, but he scored heavily and consistently on rough wickets where many contemporaries failed. By 1849 he was the recognised number three in any representative side outside Kent and was being talked of as Clarke's eventual successor as captain of the AEE. Parr would in due course succeed Clarke after his death in 1856, lead the second English tour of Australia in 1863-64, and be one of the central figures of mid-Victorian professional cricket. The 1846-49 emergence period was the foundation.
