As much as we all love Roy, the aunties love to tease my mum over the fact he’s five years younger than her, not that the age gap is even detectable, given that they’re both in their sixties.
The ages of the characters are a bit all over the place in this story. The Grand-dad who just died was 88. His twin daughters are not far off 70. Which means he was likely expecting them when he was 17. In his day men usually married before sex. I can't see a 17 year old man getting married.
Then his younger daughter is 5 years older than her second husband, and their both in their 60's so she has to be 65 or greater. But she has a teenage children we know are 17. So she had to be 43 or older carrying twins. Gee whiz.
