What is the longest discontinuous marriage? - Lemmy.World

I’m thinking along the lines of older spouse dies, younger spouse marries someone younger and becomes the older spouse. Then older spouse dies again and repeat. Has anything like this happened in a long enough chain to be significant? Is it so mundane no one cares?

Not at all an answer to your question, but a very semi-related tangent.

The last receipt of a US Civil War pension passed away relatively recently. She was a young woman who would regularly help out a local older man, a civil war vet with no kids or family otherwise. Towards the end of his days, he married her so she'd get the benefits of his pension, as things were really really tough.

It sounds like you’re thinking of Helen Viola Jackson. I didn’t know that, but it was at the bottom of your Wikipedia link :)

Ah yep, you're right that's the one I was thinking of. Both are pretty interesting, forget how young this country is sometimes.
