Hannah Frances Davidson, an American missionary from the Brethren in Christ (BIC) church, traveled there from Matopo Mission in Southern Rhodesia (present-day Zimbabwe).
Davidson and her companions subsequently embarked on the task of converting local Tonga and Ila peoples to Christianity.
In the 1950s the medical mission of the site greatly expanded due to the presence of Alvan Thuma, a physician and BIC missionary from the United States, and his wife Ardys.
The history of their involvement in Macha has been documented in the book First a Friend [1] The mission became the anchor for later Brethren in Christ mission work in Southern Zambia with missionaries expanding to Sikalongo and to Choma.
Macha Works, a cooperative organisation, partnered at Macha Mission and implemented an aerodrome, ABFA,[3] restaurant, Care House, Library and Craft Shop, ICT training center, Macha Innovative Christian School, and housing facilities at Ubuntu Campus.
