This past week on Coronation Street, Ken got a shock when Emily handed him a letter she's found hidden in her house.
The letter turned out to be from Ken's ex-girlfriend Susan Cunningham and this leads to Ken's long-lost son and grandson turning up the Street.
But who was Susan Cunningham? I couldn't remember so I did a bit of hard-core research (aka Google) and here's what I found. Susan Cunningham dated Ken around 1960-61 and only appeared in four episodes. She was played by actress Patricia Shakesby who went on to star in Howard's Way.
I wrote a summary of Corrie's first episode which introduces Susan, read it here.
You can watch Susan Cunningham on YouTube here, she's the woman in the full skirt, not the one with the dark hair (that's Beryl Bainbridge!).
