I think it's safe to say your picture is from Texas...
A branch was opened in San Antonio about 1883, and the firm's name changed to Thomas Goggan & Bros., when Goggan took into business a younger brother, Mike, born about 1854 in County Kerry, Ireland. Mike Goggan, who was working as a clerk in the Galveston store in 1880, assumed charge of the San Antonio store, which grew in importance as a center of distribution, especially because El Paso and Amarillo were good markets for the firm. The San Antonio store, called Goggan Palace of Music, was located at Broadway and Travis in the early twentieth century, and sold radios, phonographs, records, sheet music, and string and wind instruments, as well as all manner of pianos, from uprights and grands to player and reproducing pianos. The piano brands sold were nationally famous: Steinway and Sons, A. B. Chase, Schumann, Weber, Aeolian, Duo-Art, and also "Goggan." The store used the slogan "Tell the Truth and Shame the Devil" and was a meeting place for many music celebrities.
By 1885 Goggan ads announced the firm as the "largest piano house in Texas" and the "oldest music house in Texas." Nevertheless, the company's history is sketchy. City directories indicate the San Antonio store changed addresses at least twice, though the Galveston headquarters apparently remained at its original location. Branch offices also opened in Dallas, Waco, Austin, and Houston. According to his obituary in the San Antonio Express (November 27, 1914), Mike Goggan left the company and established himself in independent business in San Antonio after the deaths of his brothers (Thomas, 1903, and John, 1908), by which time the family firm had been incorporated and he had severed his connection with it. The Texas State Gazetteer and Business Directory for 1914–15 identifies Mrs. John Goggan as president of Thomas Goggan & Bros., Incorporated, with Thomas S. Goggan (a son of Thomas) as vice president and secretary. The directory also listed Mike Goggan's Musical Goods, located at 225 E. Houston in San Antonio.
