It appears that Irving Keck was involved in the decision to remove Kellogg from management of the San in 1907 (the year both Kellogg brothers were disfellowshipped from the church). In the Medical Missionary published March 1907, this paragraph shows: "Elder Irving Keck, of Bowling Green, Florida, until very recently president of the Florida Conference, was associated with the work of the Committee during the greater part of its labors. Elder Keck has prepared and issued a separate report touching important phases of the questions not included in the report of the full Committee (this was the committee assigned by the Michigan Sanitarium and Benevolent Association to report on the management of the San). This he will send out to interested members of the Seventh-day Adventist denomination without charge. Send to him direct for these, at Bowling Green, Florida".
We have that same report in the MacIvor collection.
Another resource would be to do a search on adventistarchives.org
