As we stand at the intersection of ancestry & legacy, “[we] come as [two], but stand as ten[s] [of] thousand[s].” Literally…
From 1619 to today is just over 400 years. Using a realistic historical generation length (25–30 years), that equals approximately: 14–16 generations, which means roughly 16,000–65,000 (or, more realistically, 10,000–25,000) ancestor positions for just one of us across that time span.
The mathematical and scientifically recognized “doubling rule” in genealogy says that each generation doubles as you move backward:
2 parents
4 grandparents
8 great-grandparents
16 second great-grandparents
32 third great-grandparents
64 fourth great-grandparents
128 fifth great-grandparents
256 sixth great-grandparents
512 seventh great-grandparents
1,024 eighth great-grandparents
2,048 ninth great-grandparents
4,096 tenth great-grandparents
8,192 eleventh great-grandparents
16,384 twelfth great-grandparents (Gen 14)
32,768 thirteenth great-grandparents
65,536 fourteenth great-grandparents (Gen 16)
However, by 14–16 generations back, our theoretical ancestor count begins to approach or exceed the total historical population size (only about 25,000 enslaved Africans were in the English colonies in 1700), which forces extensive overlap in family lines (called pedigree collapse) making the realistic number of distinct ancestors closer to 10,000–25,000 rather than the much larger exponential figures.
Nevertheless, for us to exist today: African men and women survived the Middle Passage; Families endured enslavement; Communities rebuilt during Reconstruction; Generations navigated the horrors of lynch mobs, Jim Crow segregation, and the Civil Rights Struggle; Families migrated during the Great Migration; Ancestors pressed forward through exclusion, struggle, faith, resistance, triumph, and hope.
Our lives are not the product of one or two stories, but the convergence of thousands. Thousands of lives, sacrifices, decisions, and survivals across approximately four centuries in America. Mathematically improbable, but historically rooted. #BabyBoyLoading 👶🏾 #ValentinesDay 🖤#BlackHistoryMonth ✊🏾
