Her father was inventor Sidney Nathaniel Davidson, and her mother is unknown to the public records; she has one sibling, her sister, Mildred Davidson Austin Smith.
Kenner patented multiple inventions in her ’40s, however, she began inventing at age six when she attempted to invent a self-oiling door hinge. Invention ran in the family. Her maternal grandfather Robert Phromeberger’s most notable inventions were a tricolor light signal for trains and a stretcher with wheels for ambulances. In 1914, her father patented a clothes presser that could fit in a suitcase. In 1980, her sister invented “Family Treedition,” a family board game.
