Members of Kurt Cobain's family who opened a rare exhibition of the singer's personal belongings in the Museum of Style Icons in Newbridge, Co Kildare on Tuesday, said they wanted to "bring him back to his roots".

The late Nirvana frontman's mother Wendy O'Connor, sister Kim Cobain and daughter Frances Bean Cobain attended the opening of the Growing Up Kurt Cobain exhibition which displays iconic possessions from his life.

Some of the items on display include the top he wears in the video for Nirvana's breakthrough hit Smells Like Teen Spirit, hand-written lyrics, sketches he made as a child and a teenager and the only known car he owned, a powder blue 1965 Dodge Dart.

The rock star's Irish roots are well known, and while Cobain believed that his family originated from County Cork, his ancestors in fact emigrated to the US from Carrickmore, County Tyrone, in 1875.

Cobain's sister Kim said that the family "wanted to bring him back to his roots" with the exhibition.

"We just wanted to bring him back to where he came from and the person that he really was as a child and try to focus more on his art and him and to show people just how silly, goofy and sweet he was. We want to bring focus back to the light-heartedness and happiness that he had in his life and not focus on all the negative crap that happened later."

"We all have a lot of Irish in us and it's our first time here and we are enjoying it very much and can't wait to see more."

His mother Wendy said: "I think it shows who he really was, the real person inside before he got famous."

The family said they will explore Ireland's countryside where they plan to "ride some horses" and "eat good food" while they are here.

Cobain and Courtney Love's daughter Frances Bean said she thinks about her dad every day.

"He's unavoidable in my life, I see a Nirvana shirt every day," she said. "My dynamic with Kurt is probably more similar to a fan's dynamic as there's almost like an untouchable thing.

"All the information I have [about him] is from stories. He's there every day of my life. On some days it feels a little frustrating, like I've had emotional breakdowns in Ubers and he's come on [the radio] and I've been like 'I needed you so much right now'. It plays out on different days in different ways."

Speaking about the collection, Frances - who is a visual artist and model, described it as one the "best experiences".

"Every time someone comes up to me and tells me how Kurt's art has altered their perspective or changed their life or informed their relationship with art or people, that is a gift. Art is transcendent and when it's good art there is no timeline for it, it's one of the most powerful things in the world and something I'm super grateful for."

"My favourite item is 'chim chim' - a little rubber monkey with this battery bomb on the back of it, I thought my mom had lost it and when I walked in I was happy to see it."

The exhibition runs until September 30 in the Museum of Style Icons Newbridge, County Kildare.
