Continuing on, note this excerpt from my first post today, Rainbow Ray Hope:

Lucas was awarded a student scholarship by Warner Bros. to observe and work on the making of a film of his choosing: Finian's Rainbow 

Note from the wiki pages of cast/crew of Finian's Rainbow:

• Fred Astaire ( May 10, 1899 – June 22, 1987) 
• Petula Clark (born Sally Olwen Clark, 15 November 1932) 
• Thomas Steele  (born Thomas William Hicks, 17 December 1936) 
• Donald Harvey "Don" Francks (February 28, 1932 – April 3, 2016)
• Francis Keenan Wynn (July 27, 1916 – October 14, 1986)

On reading the post, two other dates jive with the April 3rd death of Don Francks:

• Henry Graham Greene (2 October 1904 – 3 April 1991)
• Leicester Hemingway (April 1, 1915  – September 13, 1982)

We now have an "April 1, _, 3(x2)/ Date Sequence" pattern-cluster.

So locating a third April 3... and April 2... lets first go to the April 2nd wiki page.  Cutting   to the chase, we arrive at:

• Charles Daudelin (October 1, 1920 – April 2, 2001)

And now for the April 3 wiki page... and cutting to the chase we arrive at:

• Lionel Bart (1 August 1930 – 3 April 1999)
• Terence Kemp McKenna (November 16, 1946 – April 3, 2000)

We now have an "August 1, __, October 1/ 1st Day, Month Sequence" pattern-cluster and a "November 15, 16, __/ Date Sequence" pattern-cluster.  Cutting to the chase:

• William Richard (Rich) Stevens (February 5, 1951 – September 1, 1999) 
• Louis Eugène Félix Néel (22 November 1904 – 17 November 2000)
