William Augustus Mackworth (3 March 1825 – 4 December 1855) was a Trinidad-born English cricketer who played one first-class cricket match for Cambridge University in 1845 and another for Manchester in 1848.[1] He was born in Trinidad where his father was high sheriff and died at St Kilda, Melbourne, Australia.[2]
Mackworth matriculated at Trinity College, Cambridge in 1844 but it is not recorded if he took a degree.[2] He married in Dunedin, New Zealand, in 1852.[2] In January 1855, he was named as one of the founding "resident members" of the new Melbourne branch of Miles and Kington, a Bristol-based company of "General Agents and Commission Merchants", alongside Philip Oliphant Kington, who later played first-class cricket for Victoria.[3] His death at the end of 1855 came "after an illness of ten days".[4]
As a cricketer, Mackworth was a middle-order batsman; there is no record that he bowled nor is it known whether he was right- or left-handed.[1] He achieved little in his one game for Cambridge University, but not out innings of 10 and 28 in the 1848 first-class match between Manchester and Sheffield – a forerunner of Lancashire and Yorkshire matches – enabled Manchester to win by 11 runs.[5] He appeared for Manchester in minor matches in both 1847 and 1848.[1]
