A recent thread involved estimating the number of
generations between future King William V (b. 1982)
and Charlemagne (born 1240 years earlier). My
own data show mode, median *and* mean of path length
as 44 generations, but others thought this was high.

In these paths, what portion of links are male?
I estimate average parent-to-child age
gap as about 28 years (perhaps 26 for mother, 30 for
father) and others imply this is too low.
I'd like to mention some of the statistical biases
that can affect such estimates. I'm sure s.g.m'ers
can offer better information here than I.
The following are all reasons to expect a *true*
average path to Charlemagne to be longer (shorter
average generation) than shown in a genealogical database.
(1) Since missing mothers are more common than missing
fathers in all "old" pedigrees, the higher age of
fathers biases any database (producing, e.g. shorter
average paths to Charlemagne).
Taking the purely agnatic line of Victoria's Albert
back 25 generations, I see father's mean age at birth
as 35 years. The purely uterine line shows mother's
mean age at birth as 23 years! (Do *not* use this data
as a general estimate: Albert's pedigree is likely an
extreme case, even though both paths are mostly German.)
(2) Longer paths have more links, so more chance for
data to be missing or controversial. This effect will
bias any database (especially those omitting controversial
connections) toward shorter path lengths.
(3) One might surmise that young nobles may sow undocumented
wild oats, while older nobles might suffer undocumented
cuckolding. Either effect would, again, cause databases
to show shorter path lengths than a true picture.
(4) While the discussion focused on descents through nobility
from Charlemagne, population analysis would also be concerned
with descent through peasants from peasants. I'd assume
such paths would be longer than those from Charlemagne, due
to shorter life expectancies, right?
There are two possible biases that would operate the
other way, but I'm not sure either is significant.
(1) Descent from an heir (oldest son) might be more
likely to be recorded than descent from a younger son.
(2) Speculative and mistaken lineages may tend to have
younger parents, so longer path lengths.
The ancestry of Queen Victoria or her husband are good
places to search for long paths from Charlemagne to William:
I suppose this is because the path from Victoria to the
Heir Apparent is mostly of first-borns.

The pure-agnatic and pure-uterine ancestors of
Prince Consort Albert show a male-female age gap that
is surprisingly large. I'll show them with normal
"ancestor numbers" but remember that, these are *not*
father-mother pairs (except Albert's own parents) and
that, for example 4095 is a generation *earlier* than 4096.

By the way, I have Maria LASKARINA as 15-g granddaughter
of Charlemagne. Is this correct? If so, it provides a
49-link path from Charlemagne to future William V.
(There are longer paths than this, but it would be an
effort to find one that passes 100% expert scrutiny.)

You somehow flipped my meaning. "Otherwise" means "if not";
i.e. if mother and father are always completely unrelated, there'd
be a maximum of one descent. Trivially true, but absurd since
everyone's related. (Mine was a reduction ad absurdem to refute
someone who seemed unclear about this.)
