They're almost certainly not of "this generation" via the over-lapping side hustle.
Diogenesister, It is difficult to peer into the angels' action of Rev.7, where they "seal" or anoint the prospective GB members. Traditionally anointing happens at baptism,( Jesus, Cornelius) although most will not be inclined to also start partaking of communion then.
All generations, however defined, anointed or wicked, run consecutively anyway. A partaker could become an anointed later , as were the original 11. On age alone they overlapped with the Frantzes of this world.
The anointed generation is academic anyway. wt says they will pass away to heaven at the outset of the Great Tribulation, to fight as immortals at Armageddon.
Jesus disagreed.preemptively,
He said the generation would pass away after all these things have occurred, have happened, Armageddon included.
The wt anointed generation of 1914 needs a re-generation. badly.
