Adam Peaty's Olympic gold medal-winning performance in Rio has ensured he's a star, but he's not the only one in the family becoming well known to supporters of Team GB. His grandmother, a 74-year-old lady from Staffordshire, is on her way to becoming a national treasure.

Self-styled "#OlympicNan" Mavis Williams, of Uttoxeter, has captured online hearts with her enthusiastic use of social media.

BBC News remembers some other English grandparents who've gone viral.

Manners maketh nan

May Ashworth's Google inquiry about Roman numerals was dubbed "the politest internet search ever" after her grandson took a photo of her laptop screen and posted it online - it's been viewed and retweeted tens of thousands of times.

The search came about because the 86-year-old from Wigan likes to know when television programmes were made, and production companies still use Roman numerals on their credits.

Unsure of the figures, Mrs Ashworth took to her computer - writing "please translate these roman numerals mcmxcviii thank you."

Ben John, 25, who was visiting his nan to do his washing, said: "It made me chuckle so I thought I'd take a photo and put it on Twitter for my friends to see. I didn't expect so many other people to see it."

According to Ben, Mrs Ashworth thinks there is a physical person at Google's headquarters who looks after the searches.

"She thought that by being polite and using her manners, the search would be quicker."

Google found Mrs Ashworth's manners charming, and replied with the answer: "1998".

Geriatric1927

Peter Oakley, from Bakewell in Derbyshire, took his username Geriatric1927 from the year he was born.

He posted more than 400 videos on YouTube between 2006 and 2014 as an autobiographical series, Telling It All.

He described his work as: "It doesn't fit into any one genre; as an 86-year-old I reminisce about my life today and stories of times past. I might cook a meal or read you a story or tell you what has been happening during the week in which I upload the video."

He had more than 50,000 subscribers worldwide to his channel, commenting on events such as the London Olympics, the birth of Prince George and his life as a health inspector. His first contribution - called First Try - received more than three million hits.

He died in March 2014 aged 86, but his videos can still be seen on his channel The Internet Grandad.

Tears-of-joy rider

Iris Howard, from Epsom in Surrey, got a special surprise on her 86th birthday, when her grandson David Goodings took her for a spin in his car.

Unbeknown to her, the "radio programme" playing in the car was a compilation of recorded birthday messages from her friends and family.

The "presenter" broke off to make a special announcement: "Iris Howard is celebrating her birthday, commonly known for winning the best nan competition for 10 years in a row.

"The 86-year-old is often described as an incredible person and loved by all her friends and family."

Mrs Howard listened to the greetings, becoming increasingly emotional. Her grandson had filmed it all and posted the video on You Tube - it's since had more than 1.5 million views.

Glasto nan

Myra Galloway's message to her Glastonbury-bound granddaughter was liked by more than 15,000 people after she wrote on the festival's Facebook page rather than - as she thought she was doing - sending a private communication.

The 86-year-old, from Box in Wiltshire, posted: "I dint know you where going. make sure you've got your wellie enjoy Nan."

Tens of thousands of festival-goers reacted to Mrs Galloway's kind words, with multiple commenters writing "bless her".

The follower of fashion?

More than 5,000 people liked a tweet by Coventry City footballer Jodi Jones about his nan, who'd mistaken his trendy ripped jeans for a pair of trousers much in need of a spot of repair.

The 18-year-old says he stayed the night at his loving grandma's house and woke in the morning to find she'd kindly repaired his modish strides.

Jones says he didn't tell his nan "that that's how the jeans are", but thanked her for her work instead.

Comments on Twitter include: "Didn't have creases ironed down the middle too, by any chance?" and "God bless your nan, that is so sweet".
