Gassleins At The Keg In Philadelphia

Joseph Aloysius Gasslein, son of John Charles & Harriet (McDonough) Gasslein, of Philadelphia married Jim's great-aunt, Alice White.  John Charles Gasslein's father was John Joseph Gasslein, Jr.  Were they part of the same family remembered in the book excerpt below?  I don't know.

From "Steeplejack: Apology. pt.I. In old Philadelphia. pt. II. Paris forty years ago" by James Huneker, mentioned "The Keg" kept by the Gasslein brothers, Joseph and Charles, the sons of old man Gasslein, who had a place fifty years ago further up town on Callowhill or Noble St.

The book also told of the actor, Edwin Booth, brother of John Wilkes Booth, at "The Keg."
