Adele Key

The Deaths in 2017 site lists under April 23:

• Isiaka Adeleke, 62, Nigerian politician, Governor of Osun State (1992–1993), heart attack.^[1]

The surname Adeleke is a cryptic "Adele key".  The name Adele stands out given the recent "Adele" pattern-cluster.

• Isiaka Adetunji Adeleke ( 15 January 1955 - April 23, 2017)

Note his birthday and note from my previous post:

• The film premiered 8 January 1999 in Poland
• 15 January 1999 (Poland) 

The dates between Wikipedia and the IMDb page differ in regards to the Release dates, regardless both sets of dates stands out: January 8th is the birthday of my step son and January 15 is the birthday of both my son and life partner.  

And then from yesterdays post re Gibe Son: 

Hugh Leslie Gibb^[1] (15 January 1916 – 6 March 1992) 

As for the name Adele, note the etymology:

 Originally a short form of names beginning with the Germanic element adal meaning "noble". Saint Adela was a 7th-century Frankish princess who founded a monastery at Pfazel in France. This name was also borne by a daughter of William the Conqueror.

Perhaps Saint Adela and William the Conqueror's daughter will reveal more...
