The following excerpts are taken from Edwin W Kilbournes book "Bridge across the century", volume one, a history of 100 years of the OMS in Asia, 1901 - 2001.....

From page 161 (Korea):

At this early stage of Korea Holiness Church history, missionaries represented the greatest hope for the development of a Bible school. From 1910 to 1925 the majority of the teachers in the school were missionaries: John and Emily Thomas from Wales; Fred and Annie Briggs, William and Nora Heslop, Mr and Mrs W J Willis, and Mr and Mrs William Miller from England; Harry Woods, Helen Young, Pauline Moyer, Verna Hertzier, Emily Strong (who later married Harry Woods), John Orkney, and Paul and Myrtle Haines from the United States. Those engaged primarily in itinerating were Ida Tate and Annie Oakes (who married Fred Briggs) from England; William and Sarah Thiele, and Emia Black from the United States; and Lorenz Lassen from Denmark, who had the added assignment of supervising both building construction and maintenance. Itinerating missionaries frequently gave part-time to teaching in the Bible school. During this period of eleven years there were 46 graduates: 36 men and 10 women.

From page 219 (Korea):

The autonomy of the work in Japan diminished the need of missionaries on that field, and they began to transfer to Korea. New recruits in our homeland countries were magnetically drawn to give themselves for service in a land where God was clearly at work. Among these were Emia Black, a trained nurse, and Emily Strong, both from the United States, and Ida Tate from Hull, England. Emily Strong eventually married Harry Woods who had been in Japan with The Great Village Campaign. Others were William and Sarah Thiele, John and Anna Mae Orkney, and the William Millers. Further augmenting the company were Verna Hertzier, Helen Young, Pauline Moyer, Lorenz Lassen of Denmark, Mr and Mrs W J Willis, William and Nora Heslop and Fred and Annie Briggs from England. With this influx of missionaries, the Mission planned to place at least one missionary couple in each of the thirteen Korean provinces. Thus encouraged, the program of evangelism and the spread of the church steadily increased.

From pages 339/40 (China):

(Subsequent to the fire in June 1936 in Peiping....) While timbers still smoldered, Kilboume summoned the architects. "This is entirely a step of faith," he wrote constituents at home. There were practically no funds, but "for the training of hundreds of native preachers for North China it is imperative that we quickly rebuild." Furthermore, he proposed to erect more spacious facilities to house the envisioned increase in students. With $15,000 indemnity from fire insurance, and generous gifts from homeland friends, within four months nearly all of the needed $25,000 was in hand. Rebuilding was expected to be completed by the coming January. Interruption of classes lasted only five weeks, and when the work at last ended, the new facilities "were in pure Chinese architecture." On January 10, 1937, Eugene Erny took charge of the dedication service, with W J Willis of the British Isles preaching.

The footnote on page 340 reads:

Wood, In These Mortal Hands: p 185. Willis and his wife were asked to come to Peiping in the autumn of 1936 to briefly replace Harry and Emily Woods who had left for furlough. The Willises had served with the Woodses under OMS in Korea in the early 1920s and were close friends.

From Addenda, (British and Asian Connection) page xxvii:

By 1920, British missionaries in Korea included Ida Tate, from Hull, England, who would give a lifetime to that little land. When she retired, the Koreans honored her as one of their own. The same year, Mr and Mrs W J Willis also joined the British team. First appointed as missionaries to Korea, after one term they were asked to return and take over the responsibility as general secretary of OMS in Britain, with their office in Bangor, Northern Ireland. They would make themselves available to OMS again in 1936, going out to Peking, China, to replace Harry and Emily Woods coming on furlough. Mr Willis spoke at the dedication of the rebuilt Kilbourne Memorial Bible Institute destroyed by fire two years earlier.
