Irene Frances Rich (née Luther; October 13, 1891 – April 22, 1988) was an American actress who worked in both silent films, talkies, and radio.

[1] At age 17, she wed Elvo Elcourt Deffenbaugh at All Saints' Cathedral in Spokane, Washington on February 17, 1909,[2] after her parents talked about sending her to boarding school.

[citation needed] Rich married for the third time on April 6, 1927 in Del Monte, California, to real estate mogul David Ferguson Blankenhorn (1886–1969), at the home of William May Garland.

Blankenhorn was well known in the Los Angeles real estate market, was a longtime resident of Pasadena and San Francisco, and handled the transaction of William Wrigley, Jr. purchasing Catalina Island in 1919.

She became involved in a deadly love triangle in 1949 when Agnes Elizabeth Garnier shot and killed wealthy businessman John Edwin Owen (1881–1949).

Owen, formerly a businessman and politician from Michigan, was president of the National Apartment House Owners' Association, among other business interests, including cattle and horse ranching in Gunnison, Colorado and Riverside, California.

The Riverside County Sheriff's Department investigator said that Garnier killed Owen (who was married, but estranged and separated from his wife) and blamed Rich for coming between them.

[1] On February 28, 1950, Rich married her last husband, George Henry Clifford (1881–1959), a public utilities executive, at The Sherry-Netherland Hotel in New York City.
