Then Eyman moved from Ohio in 1828 to Carroll County, Indiana, serving in what became the Bachelor's Run and Lower Deer Creek churches.
Bachelor's Run was the first Brethren Church in Carroll County.
In 1838 trouble began between Eyman and fellow minister Peter Replogle, which resulted in a division of Church territory.
Around 1845 Peter Eyman and another minister, George Patton, advocated "variant practices" for which they were disfellowshipped by the Annual Conference in 1848.
In doctrine and practice, they were close to the Brethren from whom they evolved, faithfully observing trine forward immersion, feet washing, the holy kiss, anointing with oil, and other Brethren practices.
