TO DEBRA - SHE WHO SEEKS GENEALOGY

 

Possibly ,because I have no family to trace, I have always decried genealogy research as somewhat ridiculous.   With a science/math background I tend to look at things pragmatically.    Generations increase exponentially going downward - where as populations decrease going downward. At some point your exponentially generation count will surpass the world population.

By your ninth generation you literally have over a thousand direct ancestors.  Any one of those decedents only represent one one-thousandth of your DNA.   Realistically not enough to actually claim kindship. 

Somewhere between 1490 and 1470 your ancestors, counted exponentially, surpass the entire world population  (400 million approx. world population - 738 million ancestors - circa 1470.)

This of course is ridiculous.   Obviously along the line your generations become incestuous: wives with multiple husbands and husbands with multiple wives and sexual relations between brothers and sisters, cousins, aunts and uncles - and of course: I'm my own grandpa. 

Young women have typically started families by age twenty; therefore, I have used twenty years as the time interval for previous generations
