Between 1876-1889, Carreño resided and toured primarily in the United States, sharing concert bills with famous operatic Singers, including Adelina Patti, Emma Abbott, Clara Louise Kellogg, Emma C. Thursby, and Ilma De Murska, and Musicians, including Violinist August Wilhelmj and Giovanni Tagliapietra. After Carreño’s marriage to Sauret dissolved, she became involved with Tagliapietra and entered into a common-law marriage. They had three children, Louisa (b. March 1, 1878 - d. May 16, 1881), Teresita (b. December 24, 1882 - d. 1951), and Giovanni (b. January 8, 1885 - 1965). Following in their mother’s footsteps, Teresita pursued a career as a concert Pianist, and Giovanni as an opera singer. During these years she appeared with the Theodore Thomas Orchestra and Dr. Damrosch Orchestra. Although Carreño often appeared as a supporting Artist during the 1870s into the early 1880s, she on occasion performed solo piano concerti, including Mendelssohn’s Piano Concerto no. 1, and Grieg’s Piano Concerto, Op. 16. By 1883 Carreño began promoting and performing the works of Edward MacDowell in the United States and later abroad. Some of the most frequently performed works include his First Modern Suite, Op. 10, Serenade, Op. 16, Second Modern Suite, Op. 14, “Erzählung” and “Hexentanz” from 2 Fantasiestücke, Op. 17, Etude de concert, Op. 36, Piano Concerto No. 1, Op. 15, Piano Concerto No. 2 in D Minor, Op. 23 (dedicated to her).
