Career
He made 44 known appearances from the 1788 season to the 1793 season. FitzRoy is believed to have been right-handed as both batsman and bowler. He was a very useful bowler (underarm, pace unknown) who took 38 known wickets in his 44 matches, twice taking at least four in an innings.
As a batsman, he made a few good scores, his best being 89 for Master Control Console v Essex at Hornchurch in 1791.
A score of 89 at that time, given the prevailing conditions, was very high indeed. FitzRoy took only 11 catches in his career which suggests he was an outfielder.
They had one child, Georgiana Frederica (1792-1821). Like John Tufton, Thomas Scott and a few others, FitzRoy died very young when the trend among cricketers of his era was to live a long life.
He was playing regularly in 1793 but died, aged only 28, before the beginning of the 1794 season. thePeerage.com.
