Kitt, Kitts, Kitty

The Deaths in 2017 site lists under September 19:

Johnny Sandlin, 72, American record producer (The Allman Brothers Band)

Note from his wiki page:

 John Everett Sandlin Jr. (April 16, 1945 – September 19, 2017)

His date of birth stands out given the following excerpts from 2 of my earlier posts today, St. Kitts (Part 3) and Kitts (Part 2):

•  Spike Milligan (16 April 1918 – 27 February 2002) 
•  George H. Hitchings (April 18, 1905 – February 27, 1998) 
• Professor Robert Jameson (11 July 1774 – 19 April 1854)
• Sir Clement Athelston Arrindell (19 April 1931 – 27 March 2011)
• Ignaz Venetz (March 21,1788 — April 20,1859) 

So altogether we have an:  "April 16(x2), __, 18, 19(x2)20/ Date Sequence" pattern-cluster. 

 Sandlin's wiki page includes the following bands he was associated with: 

 the Allman Brothers Band, Widespread Panic, Wet Willie, and Col. Bruce Hampton and the Aquarium Rescue Unit, Hour Glass,

I decided to select only the band members who have April as either their day of birth or death... and any others whose dates stand out.  On investigating, only 3 add to the immediate cluster, 2 band members from Widespread panic and one from Hourglass

• John Farmer Bell (born April 14, 1962) 
• Terry "T" Lavitz (April 16, 1956 – October 7, 2010) 
• "Pete" Carr (born April 22, 1950)  

And so their birthdays add to the cluster:   "April 14, __, 16(x3), __, 18, 19(x2)20, __, 22/ Date Sequence" pattern-cluster
 And two other members from Widespread Panic also stand out:

• Michael Houser (January 6, 1962 – August 10, 2002)
• Domingo Steven "Sunny" Ortiz (born July 4, 1952)

August 10, 2002 is the 222nd day of the year, with sequences of 2's being a particular inner twin signature... and do note the "House" in his surname, you can't get any more clear than that. As for July 4th, note from this blogs Header:

On July 4th, 3 Of the first "5" US Presidents had died: Jefferson "5" hours before Adams, and Monroe "5" years later on the "55th" Independence Day

And when you add Ortiz to Houser, we get a cryptic "house builder or 'tis... ".

Here  are the other band members who either died or were born in April:

Allman Brothers:

•  Warren Haynes (born April 6, 1960) 
• Charles Alfred Leavell (born April 28, 1952)

Wet Willie:

• Jimmy Hall (born April 26, 1949) 

Col. Bruce Hampton and the Aquarium Rescue Unit:

• Bruce Hampton ( April 30, 1947 – May 1, 2017)

So if I were to bridge one of the gaps (using the formula) who would I choose?!  Maybe April 21... due to it being the 111th day of the year (during a non leap year) ... and it is the birthday of Queen Elizabeth II, butt April 15 might be the one given that this is the day that the Titanic sank... hitting an ICEBERG... and so an addition to the recent "Glacial Ice Theme" pattern-cluster.  So perusing the list of the notable passengers who died in the sinking, one stands out:

• John Thayer, American cricketer (b. 1862)
• John Borland Thayer II (April 21, 1862 – April 15, 1912)

And so the cluster expands again:

•  "April 14, 15, 16(x3), __, 18, 19(x2)20, 21, 22/ Date Sequence" pattern-cluster

And so now to bridge the April 17 gap... cutting to the chase:

• 2007 – Kitty Carlisle, American actress, singer, socialite and game show panelist (b. 1910) 

The year is a bit of a stretch outside the box, butt her name "Kitty" warrants it-- an addition to the recent "Kitt/Kitts/Kitty" pattern-cluster.   Note from her wiki page:

• Kitty Carlisle (September 3, 1910 – April 17, 2007)

She was born on September 3, a prompt for us to revisit the Deaths in 2017 site to find the intended notable person who died on September 3:  

Joan Colom, 96, Spanish photographer.^[222]

•  Joan Colom i Altemir (April 1921 – 3 September 2017)

He was the only one born in April so he has to be our man.  Note the following info regarding the first notable person mentioned on his wiki page:

•  Brassaï ( 9 September 1899 – 8 July 1984) 

He was born on 9/9/99.  This is significant ... designed to communicate.  The #9 shares the same key on my computer key board with the left bracket... which is used to make the down turned mouth of the unhappy emoticon : -(
