I don’t know, my Dad is a family of 16 kids. When my grandma passed away in 2005, they did a count of 16kids, 60 Grand Children and another 60 Great-Grandchildren, that’s almost 20years ago, those two generations are about 120 people. My Grandparents descended from pairs of people. That 120 of grand & great-grand is averaging 50 years per person times 120 is 6,000 years totaled up. That’s some lineage either way.
