Barber, Thomas an Irish Wesleyan minister, first heard the Gospel preached by Methodists at Sidare, County Fermanagh. He was convicted of sin under the ministry of John Wesley, who admitted him into the Church. His love for souls soon led him to engage in missionary work on the Londonderry Circuit. His first appointment was to Sligo in 1779. After a most active service, he became a supernumerary in 1808, and died in 1826. Barber guided Adam Clarke's earliest religious course. He was a man of agreeable eccentricities, indefatigable energy, and great success. See Minutes of the British Conference, 1826; Stevens, Hist. of Methodism, 3, 437.
