Smith's husband, Perry Barlow, whom she married on February 22, 1922, was a cartoonist for
The New Yorker magazine, drawing 135 covers over the years in addition to many cartoons. He also contributed work to ''
Collier's, The Saturday Evening Post'' and others. Because Perry was partially
colorblind, Smith helped with the color process of his work. Smith and Perry had two sons, Collins and Peter. Peter's child is Smith's only granddaughter. Dorrie carries her namesake, Dorothy "Dorrie" Barlow Thomas. After Dorothy's death in 1955, their son Peter continued the color treatments to Perry's work. ==References==
