Maggie Duckworth was the mother of Jack and Clifford Duckworth, and paternal grandmother to Terry.

In 1988, Daughter-in-law Vera recollected her first meeting with the senior Mrs Duckworth, when Jack took her back home for the first time. Vera described her as a short, thin woman, who wore a black pinny and spent the evening sat in a rocking chair by the fireplace, smoking a pack of cigarettes.

Apparently, the reason Maggie never spoke was because she was trying to figure out who Vera reminded her of - upon asking, Vera found out that she reminded Maggie of the cartoon character Olive Oyl, girlfriend of the equally fictitious character Popeye the Sailor.
