Question: Helter Skelter presented the firsthand account of the murder who was a part of whose "family"?
Context: Susan Denise Atkins (May 7, 1948 September 24, 2009) was a convicted American murderer who was a member of Charles Manson's "Family".  Manson and his followers committed a series of nine murders at four locations in California, over a period of five weeks in the summer of 1969.  Known within the Manson family as Sadie Mae Glutz or Sexy Sadie, Atkins was convicted for her participation in eight of these killings, including the most notorious, the "Tate/LaBianca" murders.  She was sentenced to death, which was subsequently commuted to life in prison.  Atkins was incarcerated from October 1, 1969, until her death – a period exactly one week short of 40 years.  At the time of her death, Atkins was California's longest-serving female inmate. "Helter Skelter" is a song by the English rock band the Beatles that was released in 1968 on their self-titled double album, often known as "the White Album".  It was written by Paul McCartney and credited to Lennon–McCartney.  The song was a product of McCartney's attempt to create a sound as loud and dirty as possible.  The Beatles' recording has been noted for its "proto-metal roar" and is considered by music historians to be a key influence in the early development of heavy metal. " Rolling Stone" magazine ranked "Helter Skelter" 52nd on its list of the "100 Greatest Beatles songs".

Lourenço, claiming to be descended from kings of Kongo and Angola, travelled to Rome in 1684 to protest to the Pope against slavery.  His petitions, which presented a firsthand account of the cruelties inflicted by slavery, supported by Capuchin missionaries, convinced the Sacred Congregation for the Propagation of the Faith and led directly to the March 20th, 1686 condemnation by Pope Innocent XI.
