"[2] She repeated this as sworn evidence in 1813, when the child became chargeable on the parish under the English Poor Laws, giving Booth's address then as Queen Street, Bloomsbury.

Their first child, Amelia Portia Adelaide Booth, was born 4 months, 2 weeks and 4 days later, on 5 October 1815, but died 7 July 1816.

He performed roles in several small theatres throughout England, and joined a tour of the Low Countries in 1814, returning the following year to make his London debut.

Booth gained national renown in England with his performance in the title role of Richard III in 1817 at the Covent Garden Theatre.

This did not stop the two from performing in the same plays; Kean and Booth acted in several Shakespearean productions at the Theatre Royal, Drury Lane from 1817 to 1821.

In 1821, Booth emigrated to the United States with Mary Ann Holmes, a flower girl, abandoning his wife and their young son.

A persistent story, but apocryphal according to some sources, is that Junius Brutus Booth was acclaimed for performing Orestes in the French language in New Orleans.

Theatrical manager Noah Ludlow, who was performing with Booth at the time at the American theatre there, recounts the actual events starting on page 230 of his memoir Dramatic Life As I Found It and concludes: "Therefore, I consider the story of Mr. Booth having performed Orestes in the French language, on the French stage, altogether a mistake arising from his having acted that character in the Théâtre d'Orléans of New Orleans in 1822, but in the English language.

[citation needed] Booth's daughter Asia wrote that her father spoke fluent French and cited a review on the subject.

During a performance of Hamlet, Booth suddenly left the scene he was playing with Ophelia, scurried up a ladder, and perched up in the backdrops crowing like a rooster until his manager retrieved him.

As the stage hand stood outside the door, Booth stuck a drinking straw through the keyhole and sipped whiskey from the bottle.

To defend himself, Flynn hit Booth in the face, breaking his nose and forever altering the actor's profile and voice.

One critic said of Booth that the "personality of the actor was forgotten, and all the details seemed spontaneous workings and unconscious illustrations of the character he represented.

Such subjective judgments are perhaps too facile, as Edwin Booth's later comment about his father certainly was: "Great minds to madness closely are allied."

To help him maintain a modicum of stability and also to ensure that he sent his earnings home to the family, Junius and Mary Ann chose their son Edwin to accompany him as his dresser, aid, and guardian.

[12] In 1852, Booth was involved in a tour of California with his sons Edwin and Junius Jr., performing in San Francisco and Sacramento, where torrential rains not only closed the theatres, but also seriously depleted food supplies.

Booth had told his first wife, at the time of his initial departure from England, that he would be touring the United States for several years, but would send her money to support her and his young son, Richard, but Booth's sister and brother-in-law later arrived with their children from England and demanded to be housed and supported in exchange for keeping quiet about his American family.

[4][13] While traveling by steamboat from New Orleans to Cincinnati in 1852, Booth developed a severe fever, presumably from drinking impure river water.
