Maria Honner: Honner, born at Enniskillen, Ireland, 21 Dec. 1812, was a daughter of Eugene Macarthy, actor and manager, who died in the Dramatic College at Maybury, Surrey, 14 May 1866, aged 78.  Educated at Cork, she lost her mother at an early age, and being thrown on her own resources, with a younger brother to support, made a first appearance on the stage at a theatre in the south of Ireland.  She afterwards played in Dublin, and as the hero of juvenile tragedy attracted the notice of Edmund Kean and William Charles Macready.  Her first important character was Rosalie Somers in Thomas Morton's "Town and Country", which she played to Edmund Kean.  An engagement in Scotland followed, and she became a popular favourite.  In 1831 she was engaged by John Farrell for the Pavilion Theatre, London, where for two seasons she was the leading attraction.  In 1833 she transferred her services to the Coburg Theatre, and, on the retirement of G. B. Davidge the lessee, removed to Sadler's Wells, where Robert William Honner was the manager.

Here he formed an association with Edwin Forrest, and played Iago to his "Othello", de Mauprat to his "Richelieu", and other companion parts.  After the death of his first wife, Mr. Conway married, in May, 1852, Sarah Crocker, a leading actress, and the two thenceforward acted together.  In 1859 they opened Pike's Opera House in Cincinnati, Ohio with a first-class company, but the engagement was not profitable, and they returned to the east.  In 1861, they visited England, and filled a short engagement at Sadler's Wells Theatre, London.  After their return they became star actors, and made an extensive and profitable tour.  Though somewhat pompous in manner, Frederick Conway was a good actor, with a fine personal appearance and a commanding delivery.  He was the father of Marianne "Minnie" Conway and Lilian Conway.
