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
