William Lockton (1878-1937) was vice-principal and assistant chaplain at the Winchester Diocesan Training College from 1910-1936, where he also lectured in mathematics. Lockton proposed a “Luke first” solution to the Synoptic Problem, which became an important stepping stone for Dr. Robert Lindsey’s new approach to the Synoptic Gospels. Lockton presented his research in an important article entitled, “The Origin of the Gospels” (1922), and in three monographs: The Resurrection and Other Gospel Narratives and The Narratives of the Virgin Birth (1924); The Three Traditions in the Gospels (1926); and Certain Alleged Gospel Sources: A Study of Q, Proto-Luke and M (1927).
