He's carrying on the family name - but not quite in the same way generations have before him.
JC Stewart has been a name synonymous with the family-run grocery store in Magherafelt for decades - but now it's going worldwide.
The 23-year-old singer songwriter has been making waves in the music world after deciding to follow his passion instead of going into the family business.
JC has amassed millions of streams on Spotify and worked with the likes of Nile Rodgers, Lewis Capaldi and Rudimental and also supported Snow Patrol, who played a big role in his early career.
Based in London, he moved home ahead of lockdown and owes some of his best work to the time he spent back in Northern Ireland.
He also made a lockdown parody video of the Friends theme tune that actress Jennifer Aniston shared on social media.
However, he's had some tough moments too - what was supposed to be his first headline tour was cancelled.
And he said he has been heartbroken about the impact the pandemic has had on his crew - who are "like an extended family" - since the live music industry was brought to its knees by the pandemic.
JC said the arts are hurting right now and more needs to be done to help.
He said: "It's the crews that are really struggling. You live with them on a bus for months, they are the best at their jobs and they are some of the most skilled men and women in the world.
"Something needs to be done because it's just insane. The economy is in ruins and I know you can't just keep chucking money at stuff but people need help and they (the Government) need to open their eyes to that."
He added: "You have to hope people are okay and check in with them as much as you can. Mental health is a massive thing that's suffering - you are taking people's livelihoods and their purpose away."
JC - which stands for John Callum, although he goes by Callum - grew up in Co Londonderry and said he's appreciating home even more since he came back ahead of lockdown.
Reflecting on his experience during lockdown he said the first two weeks were "awful" after his tour cancellation.
"I thought that was it, I thought we had got so close and it just all stopped and it was really tough to take.
"I didn't know how to produce or anything, so I bought loads of stuff online, put it in the back room at my parent's house and started producing songs - and honestly, I've ended up writing some of the best stuff I've ever done. I was more productive than I've ever been, I was doing 15-hour days.
"And since going back to London it's not been the same. There was something about those two months that were amazing and really special.
"Obviously what was going on was really terrible, but I got into a lovely pattern of writing and hanging out with my parents and enjoying Magherafelt.
"And some really fun things came out of it - I did a stupid Friends video which Jennifer Aniston shared, and spending time with my family."
He adds: "It was an amazing time to be creative and take stock of what I want out of life."
His family have always been supportive of him and growing up there was never any pressure to take on the family business, it was just a simple conversation.
"We had a chat when I was 16 or 17 and it was just never an option for me. My dad (Paul) said, 'There's two options, we look at you taking this on or I'm going to sell it and I'll do something else', and I said I thought that was the way to do it. And it's still there, the name still stands. I changed my artist name a few years ago from Callum Stewart to JC Stewart.
"I thought, my initials are JC Stewart and I'm going to take the family business in a new direction.
"One person in every generation for five or six generations has been called JC Stewart and it keeps the family DNA running through it."
He cites a music workshop in Cookstown when he was 15, which was run by musician Linley Hamilton, for sparking his song-writing passion. "They brought kids in and put you in groups and taught you how to write a song. I had just never ever thought about writing a song before. I wrote a song and, literally from that day, I've written songs every day since.
"It was one of those mad things, if that had not happened that day - it wouldn't be the same story."
And while some artists chart their success to a "big break", for JC it has been a slower journey, although he prefers that over the fear of peaking. He charts one of the most defining moments as when members of Snow Patrol attended one of his early gigs in Brighton and drummer Jonny Quinn gave him a publishing deal "on the spot". And more recently, signing to Warner Records was an "honour".
He added: "In my head I've made it, in terms of 15-year-old me. If you told him I was making a bit of a living off writing songs for people I love - you are always aiming higher - but I'm so, so lucky to be doing what I'm doing."
