Relationships and children in 1990 Quinn's first wife was actress
Katherine DeMille, the adopted daughter of

The couple had five children: Christopher (1938–1941), Christina (born December 1, 1941), Catalina (born November 21, 1942), Duncan (born August 4, 1945), and Valentina (born December 26, 1952). Their first child, Christopher, aged two, drowned in the lily pond of next-door neighbor

Francesco Quinn (March 22, 1963 – August 5, 2011),
Danny Quinn (born April 16, 1964), and
Lorenzo Quinn (born May 7, 1966). His marriage to Addolori ended in divorce in August 1997. He then married Benvin in December 1997 and remained married to her until his death.
Civil-rights activism Quinn, who experienced discrimination growing up in Los Angeles, participated in various civil-rights and social causes. He provided funding for Latino advocacy group the
Spanish-Speaking People's Congress. He assisted in fundraising efforts for the legal defense of Mexican-American youth in the racially charged
Sleepy Lagoon murder trial in 1942. While in Paris, several other prominent Americans and he composed a petition endorsing the 1963
March on Washington; the petition, which was reprinted in several high-profile publications, was intended to rally support among Americans living abroad, according to
Elliott Miller, writing in
CounterPunch. In 1969, Quinn visited with Native American student activists
occupying Alcatraz Island in protest, promising to offer assistance. In 1970, Quinn was a panelist at the Mexican-American Conference. In 1971, he narrated a documentary film by the
Equal Employment Opportunity Commission, discussing job discrimination faced by Hispanic Americans. He was a supporter of the
United Farm Workers organization led by his friend and labor activist

Painting and writing Art critic
Donald Kuspit explains, "Examining Quinn's many expressions of creativity together—his art, collecting, and acting—we can see that he was a creative genius." Early in life, Quinn had an interest in painting and drawing. Throughout his teenaged years, he won various art competitions in California and focused his studies at Polytechnic High School in Los Angeles on drafting. Later, Quinn studied briefly under Frank Lloyd Wright through the Taliesin Fellowship — an opportunity created by winning first prize in an architectural design contest. Through Wright's recommendation, Quinn took acting lessons as a form of postoperative speech therapy, which led to an acting career that spanned over six decades. Apart from art classes taken in Chicago during the 1950s, Quinn never attended art school; nonetheless, taking advantage of books, museums, and amassing a sizable collection, he managed to give himself an effective education in the language of modern art. By the early 1980s, his work had caught the eyes of various gallery owners and was exhibited internationally, in Mexico City, Los Angeles, New York City, and Paris. His work is now represented in both public and private collections throughout the world. He wrote two memoirs,
The Original Sin (1972) and
One Man Tango (1997), a number of scripts, and a series of unpublished stories currently in the collection of his archive. ==Death==
