The term "biracial" implies that an individual is an immediate interracial relationship offspring. Vanessa Williams is not an interracial relationship offspring neither are her parents nor her grandparents. In other words, Vanessa does not have a "white" parent, grandparent, or great-grandparent. Therefore, Vanessa Williams is not "biracial" by the technical definition of what that infers. However, Vanessa Williams does come from a family that has became mixed-race and continually remained mixed-race throughout the family's many generations leading up to Vanessa's very own generation. Thus, Vanessa is a Multi-generational Multiracially-Mixed (MGM-Mixed) individual, because she comes from a family that has became and continually remained mixed-race throughout its multiple generations. Vanessa Williams can be classified as "multiracial" because she has additional racial ancestries other than just one, but she self-identifies as "Black," nonetheless; and Vanessa is "black" in a socio-political sense. Although there are many erroneous sources that claim that Vanessa Williams is "biracial" or "half-white and half-black," she actually is not because she is not an interracial relationship offspring and neither are any of her parents. Vanessa Williams' father, Milton Williams, Jr. is an African-American who was born to two African-American parents--Iris Carll and Milton Williams, Sr. Milton Williams, Sr. was born to two African-American parents as well--John Hill Williams and Mary Fields. Mary Fields was the daughter of William A. Fields--a teacher who was classified as "mulatto," and who also served on the Tennessee state legislature. Iris Carll, Vanessa's paternal grandmother, was the daughter of Frank Carll. Now, Frank Carll was "biracial" because his mother, Mary Louisa Appleford, was white, and Frank Carll's father, David Carll--a pioneering Free negro who served in the Union Army, was African-American. That means that Vanessa Williams great-great-grandmother was a white woman--Mary Louisa Appleford. Now, Vanessa Williams is far more than one-sixteenth white, because, prior to the 1930 census, the majority of her ancestors on her father's side were all listed as "mulatto," which was a person of black and white ancestry to whichever degree. Now, the designation "mulatto" did NOT mean that a person was necessarily the immediate child of one white parent and one black parent, it just meant that this individual had a physical appearance that suggested both white and black ancestry. Now, Vanessa Williams' mother, Helen Williams (née Finch) is also a non-biracial African American. However, she is, similar to her late husband, a multi-racial individual who comes from a racially diverse, albeit complex, racial background--consisting of white, black, and Native American ancestors. So, the answer to the question of Vanessa being biracial is "no," however, she does come from a Multi-generational Multi-racially Mixed (MGM-Mixed) lineage. However, Vanessa Williams is Black because of the socio-political sense of what "black" means, and how that racial classification has been defined, both culturally and socio-politically, in the United States of America.
