David B. Martin: Pioneer of Mennonite Orthodoxy
From Anabaptistwiki
David Bauman Martin (1838-1920), ancestor of many Old Order Mennonites in Ontario, Canada, was also the progenitor of what we today refer to as Mennonite orthodoxy, a movement which had its genesis in the mid 20th century. Indeed there today exists two branches of the Orthodox Mennonite Church in Ontario.
