Evangelical United Brethren
In August, 1839, a camp meeting was held in this vicinity by Bishop Joseph Seybert and five preachers, which resulted in the formation of Upper Canada's first Evangelical Church congregation. This church and the United Brethren in Christ had been founded in Pennsylvania about 1800 by German-speaking settlers. In 1836 missionaries from the Evangelical Church had preached in the Niagara Peninsula and in this region. Their first church in Canada was opened in 1841 at Berlin (Kitchener), and in 1864 a separate Canada Conference was established. In later years congregations were formed throughout Ontario and Western Canada, and in 1946 the Evangelical Church joined with the United Brethren to form the Evangelical United Brethren.
