Decided to investigate 9/9/1899 and 9/9/19999

• 1899 – Waite Hoyt, American baseball player and sportscaster (d. 1984)

Waite Charles Hoyt (September 9, 1899 – August 25, 1984) 

August 25th, the day of Waite's death is the same day as my grand daughter's birthday, hence an addition to the "Targeting Family Birthdays" pattern-cluster.  Note the following etymology:

wait (n.) early 13c., "a watcher, onlooker," from Old North French wait, Old French gaite, from gaitier (see wait (v.)). From late 14c. as "an ambush, a trap" (as in lie in wait).
wait (v.) c.1200, "to watch with hostile intent, lie in wait for," from Old North French waitier "to watch" (Old French gaitier, Modern French guetter), from Frankish *wahton (cf. Dutch wacht "a watching," Old High German wahten, German wachten "to watch, to guard;" Old High German wahhon "to watch, be awake," Old English wacian "to be awake;" see wake (v.)). General sense of "remain in some place" is from late 14c.; that of "to see to it that something occurs" is late 14c. Meaning "to stand by in attendance on" is late 14c.; specific sense of "serve as an attendant at a table" is from 1560s. Related: Waited; waiting. 

HOYT: rom an English surname which was derived from Middle English hoit "stick", originally a nickname for a thin person. 

Reminds me of the "Thin man/Bomb" pattern-cluster, so the communication is ... wait on the bomb... or watch out for the bomb?!   Of course the "bomb" could be literal or metaphoric.

Note the following under Notable Deaths re the 9/9/1999 wiki page:

• 1999 – Ruth Roman, American actress (b. 1922)

In keeping with the identical number theme, note the 22 in her year of birth.  Note from Ruth's wiki page:

Ruth Roman (born Norma Roman December 22, 1922 – September 9, 1999) was an American actress. One of her most memorable roles was in the Alfred Hitchcock 1951 thriller Strangers on a Train.

She was born on 12/22/22... a significant number of 2's, and she died on 9/9/99.  Another notable person who died on the same day is:

Arie de Vroet (Dutch pronunciation: [ˈaːri də ˈvrut]) (born November 9, 1918, Oud-Beijerland - died September 9, 1999, Woudenberg) was aDutch footballer who was active as a left winger.
