David Boyd Long was born in Ireland and served as a missionary in Angola for over 30 years. The primary focus of his ministry was translating the Bible into Chokwe and teaching the Word over a wide area. When the Longs had to leave Angola because of the civil war, they returned to Canada, continuing a widely accepted ministry around the world. Mrs Long passed away in 1982; Mr Long remarried the following year; subsequently moving back to Ireland where he passed away early in 2007.
