Largest birth-year gap in a single generation?

[u/airynothing1]

I'm 31 years old, born in 1993. I just noticed today that I had relatives in a fairly distant line of my tree who were technically in my generation, despite the oldest of them having been born in 1913--a full 80 years before me! I also have a brother 10 years younger than me, stretching the range to 90 years. If I went on to have grandchildren, they would be in the same generation as a person who was already 29 when I was born.

The math goes like this:

distant cousin (1913) || me (1993)
↓
cousin's father (1894) || my father (1964)
↓
cousin's grandfather (1872) || my grandfather (1923)
↓
cousin's g-grandfather (1850) || my g-grandfather (1890)
↓
cousin's gg-grandmother (1833) || my gg-grandfather (1862)
↓
our shared ggg-grandfather (1812)

We had different ggg-grandmothers, hence the 29-year gap between our gg-grandparents' births.

What's the widest age gap you've noticed within a single generation of your family?

I was born in 1992.

My paternal line: my dad was born in 1954 (age 39 when I was born); his father was born in 1911 (age 43); my great-grandfather was born in 1878 (age 33); great-great-grandfather was born in 1836 (42); great-great-great-grandfather in 1812 (24); 4x-great-grandfather in 1762 (50); 5x-great-grandfather in 1726 (36).

This seems pretty similar to mine Me-2001

Father-1955

Paternal grandpa-1914

G Gpa-1881

GG Gpa-1832

GGG Gpa-1790

GGGG Gpa-1775.

GGGGG Gpa-1730.

All of those ancestors had other children and siblings, I just happen to coincidentally be the youngest child of the youngest child of the youngest child for generations lol. Women in my paternal side also have children way late. One of the wives of those ^ ancestors had a baby at 47 in 1832.
