Somewhat similar to DW's Dad's side. DW was born 101 years after her grandfather. Her dad was once at a Fraternity thing and met an older guy who had known his father. Told him he was Frank P's son.
Guy said "You mean grandson.".
"No, son. Dad was 64 when I was born, I was a surprise".
"Surprise? Hell, more like an effort".

16 years between FIL and his oldest sister, she was born in 1909. FIL was 37 when DW was born (1st of 3).
Don't know, how many hospitals with ERs are there in Redding? Near as I can tell from Googling, she works at the Shasta Regional Medical Center.
