Gill

 The Deaths in 2017 site lists under July 9:

• Paquita Rico, 87, Spanish singer and actress (¡Viva lo imposible!, El balcón de la luna, ¿Dónde vas, Alfonso XII?).
• Francisca Rico Martínez (13 October 1929 – 9 July 2017) 

 His film, ¡Viva lo imposible!, stands out given the "lo" within, an addition to the "Low Theme" pattern-cluster, and it also forms a cryptic phrase: long live low impossible.  The English name for the film is: Let's Make the Impossible! , released on September 1, 1958.  

One of the names on the films wiki page found in the sidebar at right stands out: by Rafael Gil,  with his surname "Gil" being similar to "Gill" the nickname of my stepson (see previous post).  Note from his wiki page:

• Rafael Gil (22 May 1913 – 10 July 1986)

 Another July 10th... todays date (see previous post), And keep in mind that Gil's birthday is one off from the day of the year where 222 days remain.  Note from the wiki pages of the cast/crew:

• Manolo Morán (30 December 1905  – 27 April 1967)
• Miguel Gila  (12 March 1919 – 13 July 2001)
• Julia Caba Alba (31 July 1912 – 14 November 1988)
• José Marco Davó  (May 10, 1895 – September 27, 1974)
• Fernando Sancho (7 January 1916 – 31 July 1990)
• Raúl Cancio (September 18, 1911 – October 23, 1961)
• Vicky Lagos (June 23, 1938)
• Yelena Samarina (16 December 1927 – 4 May 2011) 
• Miguel Mihura Santos (21 July 1905 – 27 October 1977) 

As you can see, there are quite a few July dates. Fernando's birthday is one off from my stepson's birthday.   Also keep in mind that my name is "May", and Samarina's surname breaks down into "sa marina" with Marina meaning "sea/coast" in origin that also connects to my surname "Ocean".  And her date of death re "4 May" is a cryptic "for may".  From the above dates, we now have "July 31(x2)" and a "May 10, __, July 10/ 10th Day, Month Sequence" pattern-cluster.  So investigating the July 31 wiki page... using the formula  and taking into consideration the "one off" curve ball we arrive at:

• 1992 – Leonard Cheshire (7 September 1917 – 31 July 1992) captain, pilot
• 1993 – Baudouin (7 September 1930 – 31 July 1993) King of Belgium 
• 2000 – William Keepers Maxwell Jr. (August 16, 1908 – July 31, 2000) editor, novelist 
• 2001 – Francisco da Costa Gomes (30 June 1914 – 31 July 2001) 15th President of Portugal 

From the above dates we now have a "September 7(x2)" and a "May _, June 30, July 31/ Date Sequence" pattern-cluster.  I'll leave these for you to investigate.
And note the other cast and crew found on the film's IMDb page:

• Jacqueline Pierreux (January 15, 1923 - March 10, 2005)
• Julia Delgado Caro (October 2, 1893 - 1975)
