By 1948, the first Knights of Columbus District in the Philippines has been organized, with three constituting council:  Manila Council 1000, Cebu Council 3106 and Cagayan de Oro Council 3108.  The Philippine Jurisdiction was thus officially categorized as the “Philippine District,” headed by the District Deputy.

As District Deputy, Father Willmann was vested with a full authority to supervise the constituting councils, by virtue of which authority he represented the highest KC leadership in the Philippines at that time. The period during which Father Willmann directed the affairs of the Knights of Columbus in this country as District Deputy lasted for six years, from a947 to 1953.  It was a period which witnessed the unfolding of some of the significant development in the history of the Knights of Columbus in the Philippines.
