Patrick Neill, Louis Grasmick, Michael Dann: RIIIIIIP: 9/11

The Deaths in 2016 site lists unde May 28:

Patrick Neill, Baron Neill of Bladen, 89, British barrister and life peer

Francis Patrick Neill, Baron Neill of Bladen, QC (8 August 1926 – 28 May 2016)

Preceded by	Sir Geoffrey Warnock
Succeeded by	Sir Richard Southwood

• Sir Geoffrey James Warnock(16 August 1923 – 8 October 1995) 
• Sir Thomas Richard Edmund Southwood (20 June 1931 – 26 October 2005)

We have an "August 8, ____, October 8/ 8th Day Sequence" pattern-cluster.  So as per usual, in order to bridge the gap we venture to the September 8th wiki page, and then limiting our search to the Deaths section and then investigating years having 3 identical numbers at the end:

• 1999 – Moondog, American-German singer-songwriter, drummer, and poet (b. 1916)

Note from his wiki page:

Louis Thomas Hardin (May 26, 1916 – September 8, 1999)

His middle name means "twin"  in origin and then his birthday was just 2 days before Neill's death,  hence generating a "May 26, __, 28/Date Sequence" pattern-cluster.  I consider this a prompt for us to go back to the Deaths in 2016 site under May 26 and 27, looking for anyone who stands out:

Lou Grasmick, 91, American baseball player (Philadelphia Phillies) and businessman.

• Louis Junior Grasmick(September 11, 1924 – May 26, 2016)

Michael Dann, 94, American television executive (CBS) 

• Michael Harold Dann (September 11, 1921 – May 27, 2016) was an American television executive.
