Matilda Heron was born in poverty in Labby Vale, Draperstown, Ireland in 1830 and came to the U.S. as a child. Matilda came to Philadelphia in 1842 with her parents and two sisters, Fanny and Agnes, where she took lessons from Peter Richings of the Walnut-street Theatre.
Actor Edward Askew Sothern, who was known as Douglas Stewart in the early part of his career and possibly went by the initials E.A. Sothern in his later years, moved in theatrical circles like many of the Pfaffians, including playwright John Brougham, actress Adah Menken, and theater critic William Winter. Sothern was part of the troupe that theater historian George Odell describes as Laura Keene’s best company. In addition to working with Keene, he also appeared at Barnum’s and at Wallack’s during the 1854-55 season.
Wallack’s Lyceum was located in Broadway near Broome Street. Its productions included original works by Pfaffians John Brougham, Stephen Ryder Fiske, and Fitz-James O’Brien. The Lyceum, run by James W. Wallack, was at one time the leading theater in New York City.
