Her second performance as an actress was in the company of Sol Smith Russell, which she remained with for a single season. She left the troupe following their production of Voyage en Suisse. She met her future husband, Thomas W. Ryley, while acting in this play. She acted with Rosina Vokes in slender roles for several seasons before joining Charles Frohman's comedy company. With this group she played one of the widows in the Bisson-Carre-Gillette farce, Mr. Wilkinson's Widows (1891). Bancker was paired with George Drew Barrymore who played a bigamist who was married to two different women in two cities at the same moment. Her character was married previously some years before according to the story. A reviewer for the New York Times commented on how young Bancker looked. Afterward she performed roles in such plays as The Junior Partner, His Wedding Day, and Gloriana.
Her final appearance in New York City came in a farce entitled Our Flat, staged at the Murray Hill Theatre on April 3, 1897. A few days later she was in Syracuse, New York in A Divorce Cure by Victorien Sardou. The entertainment was produced at the Bastable Theatre.
