Some freakish ones could be from old men who married very young women, and who still get their SS benefit.

A 100 year old guy marrying an 18 year old, with the former 18 year old now at 90+ would be a noteworthy, but possible, item.

At least four widows of veterans of the American Civil War (fought 1861–1865) are known to have survived into the 21st century. All were born in the 20th century and married their husbands while the women were still young and the men were in advanced age. This practice was not uncommon at the time due to the possibility of receiving pensions as dependents of Civil War veterans; the pensions were known for their generosity. Some of these unions were in name only, while others lived together as married couples. (Wikipedia)

I can’t recall which president but I saw something freaky along those lines recently. I believe Andrew Jackson’s grandson is still alive or had just died.

My first wife died in 2018. She was born in 1946. Her grandfather was born before the Civil War.

He was 72, when my first wife was born.

Fact.

After the Civil War, it was fairly common for very old family friends who fought in the Civil War would marry very young girls to allow them to collect their survivors benefits.

Many years ago (maybe 25 or 30) I heard a talk by a 97-year-old man whose father had ridden with Nathan Bedford Forrest. As an old man, his father had married a much younger woman (obviously as a woman his own age would have been too old to have children).
