3 great grand parents were more than 10 years difference and 1 grand parents and all ended their marriage by death.
“...all ended their marriage by death.”
I guess I know what you mean, but that doesn’t sound good:)
My maternal grandmother married a widower, a few of whose kids from his 1st marriage were close to her age.
No one will mention how close in age Monica Lewinsky is to Chelsea Clinton. Bill Clinton graduated from Yale law school, following his Oxford foray, a few months before Monica was born. But no judgment there!
