Name split: Sonny Boy Williamson I & Sonny Boy Williamson II

Confusion exists around the name "Sonny Boy Williamson" because there are two famous blues harmonica players of the 20th century who used that name. Music historians have dubbed them "Sonny Boy Williamson I" and "Sonny Boy Williamson II".

Sonny Boy Williamson I was born in 1914 and recorded until his death in 1948. "Sonny Boy Williamson II" was born between 1897 and 1912 as "Alex" or "Aleck Ford" (later known as Alex "Rice" Miller). Long story short, at some point in the 1940s either Miller or one of his promoters appropriated the name "Sonny Boy Williamson" to cash in on the original Sonny Boy Williamson's fame.

On IMDb, there are no separate name pages for I & II. The name page above contains biographical information for Sonny Boy Williamson II, including his portrait, death date and the highly questionable birthdate of 1899. Some of the soundtrack credits for this page should go to Sonny Boy Williamson I, though it is difficult to tell which, as they both played the same instrument and recorded in the same genre.

However, there are a few songwriting credits that we can transfer right off the bat. These are:

"Good Morning Little Schoolgirl"

• https://www.imdb.com/title/tt0179205/ - Groupies (1970)
• https://www.imdb.com/title/tt0093295/ - Jane B. par Agnès V. (1988)
• https://www.imdb.com/title/tt0101748/ - Dogfight (1991)
• https://www.imdb.com/title/tt4876250/ - Jonny Lang Live at Montreux 1999 (1999)
• https://www.imdb.com/title/tt4143508/ - Long Strange Trip (2017)

"Checkin' Up On My Baby"

• https://www.imdb.com/title/tt0118747/ - Blues Brothers 2000 (1998)
• https://www.imdb.com/title/tt0765429/ - American Gangster (2007)

These two songs are known to have been written by the original Sonny Boy Williamson and should be moved to a different page. Also, IMDb should make some attempt to differentiate the two to prevent further confusion. For example, they could adopt the practice of calling them "Sonny Boy Williamson I" and "Sonny Boy Williamson II" that most music historians use.
