Hurons-Wendat
Drawn to Methodism, Chivington became a minister. Following ordination in 1844, his first appointment was to Payson Circuit in the Illinois Conference. On the journey from Ohio to Illinois, Chivington contracted smallpox. He served the Illinois conference for ten years. In 1853, he worked in a Methodist missionary expedition to the Wyandot people in Kansas, a part of the Kansas–Nebraska Annual Conference. His outspoken views in favor of abolitionism put him in danger, and upon the advice of "Congressman Craig and other friends," Chivington was persuaded to leave the Kansas Territory for the Nebraska Territory.
