The immigration form shows that Hargreeves entered the US in 1928. This is 61 years before the births and 91 years before now.
The number 7 is stamped on Reginald Hargreeves' passport upon immigration into the United States during the episode's introduction. Interestingly, "Number 7" (Vanya) is the key, ambiguous "member" of The Umbrella Academy family and key character in which this episode ultimately surrounds.
