Richardson’s family had been settled at Rich Hill since 1611 and had frequently represented the county in the Irish parliament. He was returned unopposed in 1783, became a steady opponent of administration and would probably have opposed the Union if he had been returned in 1797.
Richardson needed Lord Gosford’s support to secure his return for the county in 1807 and was probably guided by the latter in giving a general support to ministers. The Irish secretary reported him in 1808 as having attended and as having ‘no objects that I know of’.
