[4] After completing their studies, Gilmore and McMillen moved to Long Island and from there to Paris;[4] In 1915, World War I forced them to return to the US and they settled in Provincetown, Massachusetts.
[3][4] With McMillen, Ethel Mars, and Maud Hunt Squire, they formed a group known as the Provincetown Printers.
[5] In 1923, on another visit to Paris, Gilmore re-encountered Oliver Newberry Chaffee, Jr., who had studied with her under Robert Henri in New York City.
They married in 1926, and under Chaffee's influence, Gilmore began concentrating more on her painting and less on her prints.
[1] With the other members of the Provincetown Printers, she developed a new style of printmaking using multiple colors on a single printing block, separated by white lines.
