What about Dan Sydlik and Henschel Milton, for example?
They were born in 1919 and 1920 (after 1914), and both died before the "great tribulation".
THE DEFINITION OF WT SAYS:
Jesus evidently meant that the lives of the anointed ones who were on hand when the sign began to be evident in 1914 would overlap with the lives of the other anointed ones who would see the start of the great tribulation. We do not know the exact length of "this generation," but it includes these two groups whose lives overlap.
So, are Dan Sydlik and Henschel Milton part of "this generation"?
