(Courtesy of Les Adams) Above are Lucile Browne and her real life husband, James Flavin.

Lucile Browne was born in Memphis, Tennessee in 1907. And the correct spelling of her first name is Lucile with one L, not Lucille.

She did some modeling and stage work before journeying to Hollywood and becoming a contract player at Fox circa 1930.  During the 1930s, she did about ten westerns with George O'Brien, Bob Steele, Ken Maynard, Gene Autry, Tom Tyler, Johnny Mack Brown and John Wayne.

But she is best remembered for heroine duties in six cliffhangers: DANGER ISLAND (Universal, 1931), BATTLING WITH BUFFALO BILL (Universal, 1931), AIRMAIL MYSTERY (Universal, 1932), THE LAST OF THE MOHICANS (Mascot, 1932), MYSTERY SQUADRON (Mascot, 1933), and THE LAW OF THE WILD (Mascot, 1934).

She married actor James Flavin in 1932. Both Browne and Flavin died in 1976.

After the death of her husband on April 23, 1976, Lucile visited friends or relatives in Virginia. She passed away on May 10, 1976 in a Lexington, Viriginia hospital from cardiac arrest. Did not find any death or funeral notices for Lucile on the newspaper websites.
