When Barrymore retired from theatrical work in 1906, Rankin did so as well. The couple lived for an extended period in Paris, France returning to the United States about 1910. Barrymore studied music and painting while he was there. Doris bore Lionel two daughters, Ethel and Mary. Both girls died in infancy though Mary lived a number of months.
