One of my ancestors, a farmer, married his 6th wife when he was 94. She was 18. He had 2 kids with her and lived to 107.

He had 22 kids total.

There's a joke that may be about him:

Geezers are sitting around the porch of a country store. One mentions, "Eben, I've heard you're marrying again."

"Ayup".

"I've also heard there's a considerable difference in ages."

"Ayup".

"Aren't you concerned about one not being around long for the other?"

"Well, if she dies, she dies!"

...he was 94. She was 18. He had 2 kids with her...

She had two kids with somebody, maybe even him. I would DNA test the descendants of those two.
