• Beryl Margaret Te Wiata (née McMillan, 15 April 1925 – 6 May 2017) 

Note from my previous post:

• George Herbert Hitchings (April 18, 1905 – February 27, 1998)

• Wilfred James "Wilf" Mannion (16 May 1918 – 14 April 2000) 
•  Phillip Walter Katz (November 3, 1962 – April 14, 2000

So we have an "April 14(x2), 15, 16, _, 18/ Date Sequence" and an "April 6, May 6, _/ 6th Day, Month Sequence"  pattern-cluster .   And so investigating the April 17 gap... and cutting to the chase:

• Michael Sarrazin (May 22, 1940 – April 17, 2011)
• Robert Remsen Vickrey (August 26, 1926 – April 17, 2011) 

So note the "April 17, __, June 17, __, __, September 17, October 17/ 17th Day, Month Sequence" pattern-cluster, and the "September __, 16, 17/ Date Sequence" pattern-cluster.
