"Sabbatarian Adventists" emerged between 1845 and 1849 from within the Adventist movement of William Miller, later to become the Seventh-day Adventists. Frederick Wheeler began keeping the seventh day as the sabbath after personally studying the issue in March 1844 following a conversation with Rachel Preston, according to his later report. He is reputed to be the first ordained Adventist minister to preach in support of the sabbath. Several members of the church in Washington, New Hampshire, to whom he occasionally ministered, also followed his decision, forming the first Sabbatarian Adventist church. These included William Farnsworth and his brother Cyrus. T. M. Preble soon accepted it from either Wheeler, Oakes, or someone else at the church. These events preceded the Great Disappointment, which followed shortly after, when Jesus did not return as Millerites expected on October 22, 1844.
