A TikToker filmed herself helping her 79-year-old grandma find the perfect wedding dress. Viewers have been following the bride's journey ever since.

• Danielle Jefferson took her grandmother wedding-dress shopping in a now-viral TikTok.
• Viewers became invested in her grandmother's story, asking for details about how she fell in love.

A TikToker captured the hearts of her viewers when she filmed herself helping her grandmother find the perfect wedding dress. Since then, she's been taking them on the journey of her later-in-life marriage, delighting her audience.

"My 80 year old grandma is marrying her 60 year old fiancé," wrote Danielle Jefferson in an on-screen caption of a post that showed her grandmother, Janet Merryman, trying on a white wedding gown.

The video, posted on March 3, went on to show Merryman posing in front of a mirror at a wedding dress store in her gown, using "Marry You," by Bruno Mars as the audio over the top.

Jefferson's TikTok received 1.3 million views, becoming her most viral post to date. Viewers complimented Merryman's appearance and her dress, but also said they were desperate for more information about who her grandmother's fiancé was and how she met him.

On March 11, Jefferson responded to a comment asking her to post pictures of Merryman's fiancé by sharing a slideshow of photos of the couple.

The video received hundreds of comments, with many saying they thought the couple looked great together and supporting Merryman in finding love and deciding to get married at her age.

A number of users asked for even more details about the couple, wanting to hear the story of how they decided to start dating, given the fact that there was a 20-year age gap between them.

Jefferson shared a nearly three-minute explanation of the couple's backstory on March 25, saying that her grandmother (who is actually 79, and turns 80 in June) was previously married, but in 2006, her husband died by suicide. Despite numerous health issues, Jefferson said that her grandmother remained resilient, and over a decade later she began dating her neighbor, who was going through a separation from his first wife at the time.

"I'll never forget the day that my grandma calls and says that she kissed a boy," Jefferson said, adding that the couple's romance began because her grandmother supported him emotionally during his divorce.

"They've lived happily ever after ever since," she said.

Jefferson and Merryman both spoke to "Good Morning America" about their story, and Merryman said her decision to start dating after her first marriage has helped her to smile more and find happiness.

"If there's any 80-year-old women out there, take a chance. That's all I can say," she said in the interview.

At the beginning of May, Jefferson shared a handful of videos filmed on her grandmother's wedding day, and TikTok commenters have been praising Merryman for opening herself up to romance, and said they thoroughly enjoyed seeing Jefferson rooting for her grandmother and posting about their relationship.

"What a super lovely granddaughter you are. I hope I have the same relationship with my granddaughter's. Your Grandma is stunning," one user wrote.

On TikTok, creators who share their relationships with older family members often go immensely viral, as viewers appear to love seeing intergenerational bonding on the app.

Previously, a 27-year-old TikToker who posts content about making her grandmother's fashion designs into real outfits and a 62-year-old mom who styles herself in the same clothes as her 23-year-old daughter both told Insider they believe their content appeals to people who don't have the best relationships with older relatives themselves and who want to see positive representations of families on the internet.

Danielle Jefferson did not immediately respond to Insider's request for comment.
