Historically Knanaya migrations (migration to Kodungallore and migration to Malabar), were led by Clergy and Laity together. During the second half of the 20th century a new migration to different parts of USA and Canada occurred. This latest migration was led by nurses who came to North America individually or in groups. Because of their dedication to their families, these nurses played a key role in building the North American Knanaya community. A few decades later, the Knanaya Catholic Community requested for priests from India to serve this community.
