Rev. Robert McMillan comes of Covenanter stock. He was the son of Rev. Hugh McMillan, D. D., of the Reformed Presbyterian Church. He became pastor of Herman Church May 9, 1860, and was ordained and installed by the Pittsburgh Reformed Presbytery. In the summer of 1868 he, with the larger portion of his congregation, came into the Presbyterian Church and under the care of Shenango Presbytery. He was a man full of faith and the Holy Ghost. His life was a singularly consecrated one. He gave all the powers he possessed to the service of his Master. He was busy in season and out of season, anywhere and everywhere he was about his Father's business. He was an earnest preacher of the word. His whole soul was lighted with the fire of divine love and it manifested itself in every lineament of his countenance. He was all indefatigable worker in the Young Men Christian Association, going here and there in helping to conduct meetings.
The Sabbath School Association of Lawrence Co. owes much to his consecrated enthusiasm in promoting its interests. His evangelistic efforts extended in many directions. He was a man of much prayer and
God's power in him was felt in the whole community in which he lived, He it was who introduced Dwight L. Moody and Ira D. Sankey at a meeting in Indianapolis, and his prayer was that Mr. Sankey might join Mr. Moody in his work, and his prayer was answered. But his work on earth was not of very long duration. Having labored about eight years in the Reformed Presbyterian Church and about seven in the Presbyterian Church in Herman congregation, God bid him come up higher. After a little over a year's illness he peacefully fell asleep in Jesus, May 24, 1876. His last words were, "Come, Lord Jesus."
