In 1839 Rev. James F. Flanders made an occasional visit to Janesville and preached to the people. His first sermon was delivered in the bar-room of the public house, which stood on the present site of the Myers House. Subsequently he preached in an unoccupied log house opposite where Lappin's Block now stands. The services were next held in school houses, some log and others frame, until the erection of the Court House in 1842. Thereafter the court room was occupied and used alternately by the different religious denominations. The Rev. James McKean was the first Minister who preached regularly in Janesville. The place was taken into the Troy circuit in 1840, and Brother McKean visited it once in four weeks. This year Rev. Julius Field held the first Quarterly Meeting in Janesville. In the spring of 1841, Brother McKean formed a class and appointed J.P. Wheeler Leader, but during the following winter the members all left the place. Janesville appears first in the Minutes as the head of a charge in 1841, with Rev. Alpha Warren as Pastor. At this time it was connected with Platteville District, and the Presiding Elder was Rev. H.W. Reed. Brother Warren was succeeded by Rev. Boyd Phelps, who organized a class in the spring of 1843, consisting of nine or ten members, with John Wynn as Leader. Rev. Lyman Catlin, who came in 1844, was the first resident Pastor. He was formerly a Professor in Mt. Morris Seminary. During the winter his wife, who was a lady of fine culture, taught a select school in the village. Brother Catlin preached in Janesville on the morning of each Sabbath, and in the afternoon alternated between Union and Johnstown. The following year, Rev. T.W. Perkins was appointed to the charge, but in consequence of ill health, he was soon obliged to resign. His place was supplied by Rev. Stephen Adams, of Beloit. In 1846 Rev. John Luccock was the Pastor, and was followed the next year by Rev. Wesley Lattin, who remained two years. Brother Lattin was very popular with all classes, and his labors were blessed with an extensive revival. During his Pastorate the Society erected a small frame church, 35 by 25 feet in size. It was opened for worship in the fall of 1848. The location was on the opposite side of Centre Street, and a little west of the present edifice. A Parsonage was also erected the same year. Both of them, however, were sold when the grounds were purchased for the new Church. It was during the Pastorate of Brother Lattin that the first donation party ever held in Janesville, was given. The company assembled at the residence of Mr. and Mrs. John Wynn, where Brother Lattin boarded. The ladies furnished the table with all the luxuries the village afforded, and the affair was considered a grand success.
