Genealogical best practice assumes a generation of 20 - 25 years when the actual lineage is unknown, so AD 1500 = 500 years ago, err on the cautious side and assume 20 generations, that's 1,084,576 branches on the family shrub at 1500. And I know four of them.
If you err on the liberal side and assume a generation of 20 years, that 1.08 million branches becomes a staggering 33.55 million branches.
If you continue with the 20 year generation assumption and take it back to the year 1000, there's 1.1 quadrillion branches on that bush
