Well … at least for the names of her boys.
This is from “How to Tell Someone’s Age When All You Know Is Her Age”.
What this shows is the first half of all people who share the same first name on the right of the red dot. The red dot shows their median age.
I’m a David, and I turn 50 this week. This puts me about 3 years to the right of the median age for my name. My older brother is a Robert, and he’ll turn 59 later this month, perhaps 6 years to the right of the median for his name.
So, back then, my mom (and my late father) were ahead of the curve on both names. Not on the bleeding edge, but definitely early adopters.
(For those who know my parents) who would suspect that?*
* FWIW: I try to convince my wife that my dad was an early adopter of new technology up until his mid 50’s (the early 80’s). She doesn’t believe me. But we had a VCR before anyone else. And he bought the mod new car (it was a lemon, but who knew at the time), the Chevy Citation in 1980. And we had calculators in our house before any of my friends did. Although we missed the boat on digital watches, our house was known among my friends for its large number of digital clocks (one of which still runs in our bedroom almost 40 years after he bought it at Radio Shack).
