Dec. 23, 1862 Fayette Lafayette County Wisconsin, USA
His parents were Silas L. Davis and Phoebe (Bennett) DAVIS. His family had moved to Vermont and his brother, Rev. Jairus E. Davis was in a protracted meeting when Isaac G. declared that from 'from that moment on he was for the Lord.' He began to feel it his duty to preach, and in 1838, he began holding meetings and studying with reference to the great work. His efforts were favorably looked on and the Huntington Quarterly Meeting of Freewill Baptist, gave him license in June 1839 to preach. He was ordained the next year on the 26th of Sept. 1840. He was accepted by the Missions Board as a foreign missionary, but it was finally concluded that his health would not endure the climate of India. However, his heart was always enlisted in the cause of Missions, and he gave of his scanty means, as well as his life going and preaching, to help. While attending Biblical School at Lowell, he labored with the church in Roxbury, MA, which was greatly increased in strength and numbers.
In Aug. 8, 1843, he was married to Almira Bullock, in Lowell, Mass. They spent one year in Portsmouth, NH, then two years of faithful service to Deerfield, NH. A trip to Nova Scotia and New Brunswick was made where his labors were successful.After a three-month supply of the desk at Lawrence, he removed West.
For several years, with the exception of a year or two spent in Elgin, Ill., most of his time was given to missionary labors in Boon and McHenry Quarterly Meetings and in other parts of Illinois and Wisconsin.
In 1855, he took the pastoral care of the FWB Church in Fayette, WI, where (with exception of one year in Warren, Ill) he continued faithfully until his death. He enjoyed the confidence of his congregation. In Dec. 1862, he served as moderator in Quarterly Meeting, apparently in good health; was immediately taken ill, and died in eleven days. Prof. Ransom Dunn, whom he had selected, addressed a large and deeply-affected audience upon the occasion, from II Corinthians 4:17-18.
His life and example were unusually blameless. His friends were many; his enemies, none. He left the inestimable treasure of a good example to the world.
He left four brothers,--Mr. Silas A. Davis, the Yearly Meeting Clerk; Deacon W. Bennet Davis, and Revs. Jairus E. and Kinsman R. Davis. Also, three or four sisters, and an aged father, who, for more than fifty years, has been a faithful member of the Freewill Baptist Denominaton. His own family consisted of a daughter and three sons, the oldest of whom went in the army, and the youngest--a child two years old--to heaven, having departed two days in advance of his father. He was aged 43 years.
