Career
Minch was first elected at the 1892 general election as an Anti-Parnellite candidate, unseating the sitting Parnellite Member of Parliament James Leahy. He was re-elected unopposed in 1895 and also in 1900, on the latter occasion as an Irish Parliamentary Party candidate, since the split in the party had been resolved earlier that year. He resigned his seat on 12 May 1903, by the procedural device of taking the post of Steward of the Manor of Northstead.
Minch was also one of the first councillors elected to Kildare County Council, when it was created in 1899.
He died at his residence, Rockfield House, Athy, County Kildare, in 1921.
