Vera Duckworths Son

I might be imagining this but many years ago wasn’t there a storyline that Terry wasn’t actually Jack Duckworths son
Does that ring any bells with anyone else

"Reading a letter penned to him by Vera in case the worst should happen, she admitted to Jack a fling early in their marriage which cast doubt on Terry's paternity. Jack admitted to Curly that he knew of the affair, but also had no doubt in his mind that Terry was his son as he reminded Jack too much of himself. "
