Jack Boothman RIIP May 10, 1916 : John Wilkes Booth Born May 10, 1838

The Deaths in 2016 site lists under May 10:

Jack Boothman, 79, Irish sports administrator, President of the Gaelic Athletic Association (1994–1997)

What immediately stands out is his surname, a rare enough name that one would not forget if you heard it before, and such is the case with Abraham Lincoln's assassin John Wilkes Booth.  So note from his wiki page:

• John Wilkes Booth (May 10, 1838 – April 26, 1865) 

Boothman died on Booth's birthday, hence generating a "May 10 (x2)/Date Sequence" pattern-cluster. Since the inner twin world have a propensity for generating clusters consisting of groups of three, I consider this a means of prompting us to investigate the May 10 wiki page.   As per usual, because the lists found there on the date pages are long, I generally limit my search by investigating only the years having 3 identical numbers at the end, and choosing the one who stands out the most, note the following:

• 2000 – Jules Deschênes, Canadian lawyer and judge (b. 1923)

Note from his wiki page:

• Jules Deschênes  (June 7, 1923 – May 10, 2000)  

His birthday stands out given that it's the birthday of Trish MacGregor (co author of synchrsecrets blog and novelist), another key player in the inner twin world's "Starr Family Production".  
The etymology of his surname is:

• Deschênes: "Chenes" is French for "oak tree". In French, "Des" means more than one. "Des"+ "Chenes"= Deschenes meaning "Many oak trees."

His surname is also close enough to French "des chien" which translates as "dogs", which is an addition to the recent "Wolf/Dog/Fox/Canine/K9 Theme" pattern-cluster.   As for the name Jules, it's etymology is "downy bearded", butt it's also phonetically identical to "jewels" (another strategic design influence of the inner twin world.  Note the etymology:

• jewel (n.) late 13c., "article of value used for adornment,"... from Latin jocus "pastime, sport," in Vulgar Latin "that which causes joy"
