HBCU: Lincoln University's Sister School PA

What is the sister school of Lincoln University, PA?

I am trying to find out a school that is connected to them like Spellman is connected to Morehouse.

Three institutions of higher education were established for black students prior to the Civil War. Each was established by a religious denomination. The Institute for Colored Youth in Philadelphia was established in 1837 at the behest of a Quaker, Richard Humphreys. Established originally as a school for boys, by the 1850s it had become a prominent coeducational private primary and high school. It moved to Cheyney, Pennsylvania, at the turn of the century and became Cheyney State College by the 1920s. Lincoln University was also established in Pennsylvania prior to the end of the Civil War. Established by the Presbyterian Church as the Ashmun Institute for black males in 1854, this institution obtained collegiate status before any other founded for black students. The primary mission of Lincoln was to educate ministers to evangelize in Africa and to provide religious leadership to blacks in the United States. In an attempt to produce black leaders and professionals after emancipation, Lincoln established a law school and medical school. However, both closed in 1873. In 1953, the institution became coeducational. Wilberforce University was established in 1856 by the African Methodist Episcopal Church in Ohio shortly after the founding of Lincoln University. While institutions of education founded for blacks by whites were overwhelmingly single-sex, African Americans believed education important for both men and women and established coeducational institutions. In addition, black-founded colleges employed black faculty and staff of both sexes. For example, Wilberforce employed the well-known Oberlin graduate Mary Church Terrell in 1884 as well as the young Harvard-and German-trained W. E. B. DuBois in his first faculty position in 1894. These institutions offered liberal-arts and professional courses as well as teacher training.
