Did Frederick Wentworth tell anybody about the engagement?

I am listening to the Persuasion audio book and when the Crofts move to Kellynch, he talks freely to his sister about Anne the broken engagement.

I think it is very unlikely that he told anyone, not even her. Most likely his sister was somewhere on a ship when he got engaged. And I am sure the Crofts wouldn’t have rented Kellynch Hall if they knew what happened.

What do you think? Did he tell anybody about what happened between them?
