The Deaths in 2019 site lists under September 23 and 22:

Joseph Peter Wilson, 84, American Olympic cross-country skier (1960)

• Joseph Peter "Joe Pete" Wilson (May 22, 1935 – September 13, 2019)

Carl Ruiz, 44, American chef and television personality, heart attack 

• Carl Ruiz (April 4, 1975 – September 21, 2019)  

Both birthdays stand out, butt Wilson's was added late.   May 22 is one off from May 23, the day of the year where 222 days remain.  April 4 is 4/4 (aka $/$), and another thing that stands out about him is his twin age at death, 44!!   Note as well from my previous post:

• John II Casimir (22 March 1609 – 16 December 1672)
• Arseniy Petrovych Yatsenyuk (born 22 May 1974)
• Borys Illich Oliynyk (22 October 1935 – 30 April 2017) 
• Mykola Vitaliyovych Lysenko (22 March [O.S. 10 March] 1842 – 6 November [O.S. 24 October] 1912) 

• Dmitry Stepanovich Bortniansky ((c.27 October 1745 – 2 April 1777)
• Oleksandr "Oles" Honchar (3 April 1918 – 12 December 1995)
• Bolesław-Jerzy II (1305/1310 – April 7, 1340)  

The inner twin world tend to make connections like this, where two clusters now emerge: an "April 2, 3, 4, __, ... 7/ Date Sequence" pattern cluster, and a "March 22(x2),...  May 22(x2), / 2 each, 22nd Day, Month Sequence" pattern cluster ... so a prompt to investigate October 22, looking for a 2nd.  I decided to see if the wiki pages of April 5 (the gap in the first cluster) or October 22nd wiki pages to see if any notable Ukraine's are listed in either the birth or death section.  I found  5, all of whom are on the April 5 wiki page!!

• 1949 – Judith Resnik, Ukrainian-American engineer and astronaut (d. 1986)

• Judith Arlene Resnik (April 5, 1949 – January 28, 1986) 

• 1969 – Pavlo Khnykin, Ukrainian swimmer

• Pavlo Khnykin (born April 5, 1969)

• 1975 – Serhiy Klymentiev, Ukrainian ice hockey player

• Serhiy Volodomyrovych Klymentiev (born April 5, 1975)

• 1992 – Dmytro Ryzhuk, Ukrainian footballer

• Dmytro Ryzhuk (born 5 April 1992)

Only one is dead... Judith Resnik, so she's our next lead.  She died when the Space Shuttle Challenger was destroyed during the launch of mission STS-51-L .  As to her date of death, January 28, note from my previous post:

• Gene Sharp (January 21, 1928 – January 28, 2018) 

Gene was born and died in January... and January 21 is also the birthday of my daughter.  Note the cryptic communication in the surname "Sharp"... also an addition to the "Remove A Letter Makes a Word" pattern cluster... making "harp".   I googled to see if I could find the most famous Harpist, and was brought to:

Carlos Salzedo (6 April 1885 – 17 August 1961)

So what are the chances of THAT?!  And so completing the cluster:  "April 2, 3, 4, 5, 6, 7/ Date Sequence" pattern cluster.  
I also checked the September clusters (investigating the gaps) from the previous post, and there were no Ukrain's listed, butt one person peaked my curiosity because by "accident", I hit on the link that brought me to an image of his submarine, and so I ventured to his wiki page and found: 

Narcís Monturiol i Estarriol (28 September 1819 – 6 September 1885) was a Spanish Catalan artist and engineer. He was the inventor of the first air-independent and combustion-engine-driven submarine.

Hmmm, born and died in September!!
