I don't know to much about her, but she made a good impression on me in Randolph Scott's Return Of The Badmen where she played a reformed tomboy outlaw called Cheyenne, who becomes a telegraph operator, before meeting a sorry end at the hands of Robert Ryan's Sundance Kid.
She also impressed as the dance hall girl in love with Randolph Scott's Bat Masterson in Trail Street, but again was killed by the bad guy, in this case Steve Brodie.
Anne also appeared in several Wild Bill Elliott B westerns and I gather she's a good opera singer. Ann was married for yrs to Robert Sterling until his death just a few yrs ago. She's now 85.
