Question: Who was the sibling of the president, other than Taft, that the Jenkins Orphanage played for?

Knowledge 1: Charleston, South Carolina
As many as five bands were on tour during the 1920s. The Jenkins Orphanage Band played in the inaugural parades of Presidents Theodore Roosevelt and William Taft and toured the USA and Europe. The band also played on Broadway for the play "Porgy" by DuBose and Dorothy Heyward, a stage version of their novel of the same title. The story was based in Charleston and featured the Gullah community. The Heywards insisted on hiring the real Jenkins Orphanage Band to portray themselves on stage. Only a few years later, DuBose Heyward collaborated with George and Ira Gershwin to turn his novel into the now famous opera, Porgy and Bess (so named so as to distinguish it from the play). George Gershwin and Heyward spent the summer of 1934 at Folly Beach outside of Charleston writing this "folk opera", as Gershwin called it. Porgy and Bess is considered the Great American Opera[citation needed] and is widely performed. [SEP] Knowledge 2: Taft Bridge

Roosevelt had served as president from 1901 to 1909, and Taft had won the 1908 Republican president nomination with Roosevelt's support. Displeased with Taft's actions as president, Roosevelt challenged Taft at the 1912 Republican National Convention. After Taft and his conservative allies narrowly prevailed at the Republican convention, Roosevelt rallied his progressive supporters and launched a third party bid. With the support of William Jennings Bryan and other progressives, Wilson won the Democratic Party's presidential nomination on the 46th ballot. Meanwhile, the Socialist Party renominated its perennial standard - bearer, Eugene V. Debs.
Knowledge 1: Charleston, South Carolina
The Jenkins Orphanage was established in 1891 by the Rev. Daniel J. Jenkins in Charleston. The orphanage accepted donations of musical instruments and Rev. Jenkins hired local Charleston musicians and Avery Institute Graduates to tutor the boys in music. As a result, Charleston musicians became proficient on a variety of instruments and were able to read music expertly. These traits set Jenkins musicians apart and helped land some of them positions in big bands with Duke Ellington and Count Basie. William "Cat" Anderson, Jabbo Smith, and Freddie Green are but a few of the alumni from the Jenkins Orphanage band who became professional musicians in some of the best bands of the day. Orphanages around the country began to develop brass bands in the wake of the Jenkins Orphanage Band's success. At the Colored Waif's Home Brass Band in New Orleans, for example, a young trumpeter named Louis Armstrong first began to draw attention. [SEP] Knowledge 2: Taft Bridge
