if these are wt old timers, partakers, ranging in age at death from `40 to 80, with an overlap of 20 years each, that would give them only 1914 + 80= 1994 as the date of the endgame. failed already.
better to go with David Splane's overlapping groups of super centenariens, older than Fr. Fr. Franz,( 1914 + 161= 2075. )
No disrespect for the dead intended, decorate, seed flowers on that bleak site instead
