Ion (X2)

Note the following info on a notable person just added to the Deaths in 2017 site under June 3:

David Choby, 70, (January 17, 1947 – June 3, 2017) Bishop of Nashville... fall

His birthday stands out, note this info regarding recent notable deaths :

• Sonja Sutter (17 January 1931 – 1 June 2017) actress
• Niels Helveg Petersen (17 January 1939 – 3 June 2017) Foreign Affairs Min. 
• John K. Watts (21 January 1937 – 3 June 2017) football player, broadcaster
• John M. May (January 21, 1950 – May 31, 2017) politician
• Derek Neilson (23 January 1959 – May 31, 2017) footballer
• Robert, Curtis Jr. (January 15, 1990 – May 26, 2017) basketball player
• Lawrence Jenkins (January 29, 1924 – May 28, 2017) WW II vet memoirist) 
• Ramon Campos Jr.(January 31, 1925 – May 29, 2017) basketball player
• Graham Webb (13 January 1944 – 28 May 2017) racing cyclist champion

So not only do we have two persons passing away on June 3 who are also born on January 17, we have a third born on the same day, but who had died just two days before.  Altogether the cluster

•  "January 13, 15(x3), 17(x3), 19, 21(x4), 23(x2)... 29, 31/Uneven Number Date Sequence" pattern-cluster.

And so now to investigate January 17.  Using the formula we arrive at:

• Ion Rațiu (6 June 1917 – 17 January 2000) 

First of all note the "Ion" name connection with the surname "Watts" above... a "Watt/Ion Theme" pattern-cluster.  His birthday and the birthday of Trish MacGregor generates a "June _, 6, 7 / Date Sequence" pattern-cluster and an "Off by One" pattern-cluster, and so cutting to the chase:

• Iona Brown (7 January 1941 – 5 June 2004)

The Ion in Iona being the key... and note her birthday that's also an uneven day in January... AND, note this info regarding another recent addition to the Deaths in 2017 site:

• Juan Goytisolo (5 January 1931 – 4 June 2017) 86, poet, novelist 

And so the cluster expands now into a:

•  "January _, _, 5, 7, _, _, 13, 15(x3), 17(x3), 19, 21(x4), 23(x2), _, _, 29, 31/Uneven Number Date Sequence" pattern-cluster.
