She married Albert J. Robertson in 1918, and with him lived in Minneapolis until 1924, when the couple relocated to Des Moines.
There they remained until 1953, when Albert received a position in the Eisenhower administration and the couple moved to Washington, D.C. Persis at this time gradually left lithography behind, but she continued in creative pursuits, taking up paper cutting later in life.
[2] She presented work in solo exhibitions as well, and often won prizes at the art salon of the Iowa State Fair.
She was also active with her husband in artistic circles in Des Moines; the two sat on the planning committee for the Des Moines Art Center, and she started the Art Students Workshop at the public library with Florence Cowles Kruidenier.
