Meet John McCubbin, White House police officer in 1922, recently promoted to head the force. Yes, he looks a little stiff.
He was born in Virginia to a Scottish father and English mother. His wife, Hattie, was from Maryland, and together they had two daughters, Pauline and Bessie.
According to the 1920 (and 1930) U.S. Census, the family was living at 218 4th St. SE.
