Butcher was born in Danesfort, County Kilkenny, the son of Samuel Butcher, a distinguished naval commander, and Elizabeth Anne Herbert. He graduated from Trinity College, Dublin in 1829 and joined the clergy of the Church of Ireland.
Between 1837 and 1852 he was a Fellow of Trinity College, Dublin and in 1849 and became a Doctor of Divinity.

Butcher married Mary Leahy, daughter of John Leahy, on 23 November 1847. Together they had six children. His second son was John Butcher, 1st Baron Danesfort and his eldest daughter married Thomas Spring Rice, 2nd Baron Monteagle of Brandon. Butcher caused controversy in Anglo-Irish society when he committed suicide on 29 July 1876. The inquest into his death decided that this was the result of a temporary insanity brought on by fever.
