Ada Clare (whose given name was Jane McIlheny) was born in South Carolina. As Thomas Gunn, a contemporary of Clare, describes she "made an attempt – several attempts – to become a tragic actress, but despite any amount of puffery on the part of fellows who knew her (or wanted to know her in a scriptural sense) failed. She had money and aspired for 'fame' only" (Gunn vol. 11, 160). She received a small inheritance upon her parents' deaths, which she used to travel to Paris.
While William Henry Fry’s presence at Pfaff’s remains unconfirmed, he is listed among the many associates of Ada Clare, the “Queen of Bohemia” (Rawson). A native of Philadelphia, Fry was born into a prominent native American family to parents William and Anne (nee Fleeson) Fry. His father was the publisher of the National Gazette, and his mother was the granddaughter of Judge Plunkett Fleeson. Having displayed musical talent at an early age, Fry taught himself to play the piano after listening to his older brother's piano lessons.
Born in rural Chester County, Pennsylvania, Bayard Taylor's ancestors were Quakers with ties to William Penn. Taylor began writing poems as a child and served an apprenticeship at the West Chester Village Record. Rufus Wilmot Griswold, editor of Graham's Magazine, encouraged Taylor to publish his first volume of poetry, Ximena (1844). He traveled to Europe soon after; before leaving, he visited New York and met Nathaniel Parker Willis, a frequenter of Pfaff's and an admirer of Edgar Allan Poe.
