A little off topic but this might help to follow the III's.
Ralph Sr is Ralph Jr's father. Ralph Jr is Ralph III's father. Ralph III is our current Ralph. All of these Ralph's get me so darned confused I wanna Ralph.
If you are confused by Ralph III try figuring out the Adam Clayton Powell's.

There was Adam Clayton Powell Sr. (a friend of renowned German Theologian Dietrich Bonhoeffer)
Adam Clayton Powell Jr. A congressman from NY for many many years (followed by Charlie Rangel)
and then there is:
Adam Clayton Powell III
2 Adam Clayton Powell IV's and
Adam Clayton Powell V (a record holding Swimmer at Columbia University).
from the wikipedia on Adam Clayton Powell Jr.

Personal
Adam Clayton Powell Jr. State Office Building at Adam Clayton Powell, Jr. Boulevard and 125th Street in Harlem.
His first wife was nightclub entertainer Isabel Washington, the sister of actress Fredi Washington. Powell adopted her son Preston, from a previous marriage.
Powell and his second wife, singer Hazel Scott, had a son, Adam Clayton Powell III. Adam Clayton Powell III is Vice Provost for Globalization at the University of Southern California (USC) and one of the world's leading authorities on the use of the Internet for journalists. He named his son Adam Clayton Powell IV.
Powell and his third wife, Puerto Rican Yvette Diago, had a son Adam Clayton Powell Diago, so named in the matrilineal tradition of some Latino cultures. This son changed his name to Adam Clayton Powell IV when he moved to the mainland from Puerto Rico to attend Howard University. This caused confusion because his nephew, only 8 years younger than he, was also named Adam Clayton Powell IV.
The politician A. C. Powell IV was elected to the New York City Council in 1991 after a special election and served for two terms. He also served as a New York state Assemblyman (D-East Harlem) for three terms. He named his son Adam Clayton Powell V. In the 2010 Democratic primary election, A. C. Powell IV lost his challenge to the incumbent Charles B. Rangel for the right to run for Congress in his father's District.
