One might suspect that if the generations turn over much further apart than 30
years over time then there could be some missing generations. My generation
turnovers range closer to about 25 than to 30 years. It might be possible to
spot the general time period in which there is a suspected problem with
missing generations by checking by 400 year periods. As a rule of thumb I
expect about 4 generations each 100 years. 12 generations in 400 years would
yield about 33 years while 19 generations would yield about 21 years. The
longer the time period the more suspect 33 years and 21 years would seem to
be.
