Here’s a brief note in the December 9 1950 Toronto Daily Star about a 50th wedding anniversary:
As usual with these, I ghoulishly looked Mr. Wall up in the Toronto city directories to see how long he lasted after this event. The record is inconclusive: a Henry Wall appears at 38 Fernwood Park Avenue until 1956. He’s not there in 1957, but two Henry Walls disappear and one appears at a different location in that directory, so there’s always the possibility that he moved to a new home at the age of 90. You never know: perhaps he’s still around and he’s still moving.
