Lucius Roy Holbrook (April 30, 1875–October 19, 1952) was a Major General who commanded of the United States Army's Philippine Department from 1936 to 1938. While stationed at Boise, Idaho, Holbrook met Henrietta Coffin, (January 7, 1877 – March 28, 1965), the daughter of Frank R. Coffin, a merchant and baker and Charlotte Irene (Quivey) Coffin. They were married on June 7, 1899, at the Presidio of San Francisco, California. Mrs. Coffin was reportedly the first Caucasian woman to enter Peking, following the Boxer Rebellion.
