Princess Eileen was born in Chester, England. She was the daughter of George Johnston, a landscape gardener, and his wife, Alice (née Percival).

She was married twice, being widowed on both occasions. Her first marriage was to Swiss-American Captain André de Coppet (1892 - 1953), DSC, late of the US army on 6 November 1943 in New York City. They had no children. In 1953, Eileen was widowed for the first time when André died in Lausanne, Switzerland, on 1 August 1953.

She married Carol Victor on 8 September 1966 in New York City. They later moved to England, and lived in Cheyne Walk, Chelsea, London. In 1973, Eileen was widowed for a second time when Carol Victor died at Munich, Bavaria, on 8 December 1973 (buried Neuwied am Rhein). The house became extinct on his death as he had no children, and no arrangements had been put in place for a successor.

Princess Eileen died in New York on 1 September 1985.
