Lewis and Mary E. Hadden are listed among the original members of the Otsego, Michigan, Seventh-day Adventist Church, organized by Joseph Bates in 1861. They had moved to Otsego from New York in the 1850s. There is reference to an “L. Hadden” in the Review as early as 1857. 1EGWLM 837.2
Lewis Hadden is probably the “Brother Hatten” who, according to Ellen White's diary, was present at Sabbatarian meetings in Otsego on January 8 and 9, 1859, when there was a tense standoff with the followers of Gilbert Cranmer. Hadden remained a member of the Otsego church until his death in 1893. 1EGWLM 837.3
