Prince Philip has passed away at the age of 99, after battling health problems for the last few years.
Sophie, Countess of Wessex has described the Duke of Edinburgh's final moments as "peaceful".
Prince Andrew, Prince Edward, his wife, Sophie, and their daughter, Lady Louise, 17, attended a small church service at the Royal Chapel of All Saints in Windsor on Sunday.
They chatted to members of the congregationas well as people who work on the Windsor estate to thank them for their support particularly over the last few days.
Andrew said the death of Prince Philip has left a "huge void" in the Queen's life.
Andrew, the third of Philip and the Queen's four children, told well-wishers that his mother "described it as having left a huge void in her life".
"We've lost, almost, the grandfather of the nation," he said. "And I feel very sorry and supportive of my mother, who's feeling it probably more than everybody else."
Edward called Philip's death a "dreadful shock" but said the 94-year-old Queen was "bearing up".
Sophie said the monarch was "thinking of others before herself".

She said Philip's death at Windsor Castle, which came three weeks after he was discharged from a month-long hospital stay, was "peaceful".
"It was right for him and it was so gentle. It was just like someone took him by the hand and off he went," Sophie told well-wishers. "It was very, very peaceful and that's all you want for somebody, isn't it?"
Princess Anne paid tribute to her father as "my teacher, my supporter and my critic".
As hundreds of well-wishers continued to leave floral tributes outside the gates of royal residences in memory of Philip, Anne said her father "leaves a legacy which can inspire us all".
"You know it's going to happen but you are never really ready," Anne said of Philip's death on Friday, at the age of 99.

In a message released by Buckingham Palace, Anne praised Philip's "ability to treat every person as an individual in their own right with their own skills", a nod to the many charities and other organisations he was involved with.
"I would like to emphasise how much the family appreciate the messages and memories of so many people whose lives he also touched," she said. "We will miss him, but he leaves a legacy which can inspire us all."

Charles paid his own tribute to his "dear Papa" on Saturday, and said he "would have been amazed by the reaction and the touching things that have been said about him".
Both palace and government officials urged people not to come in person to pay their respects because of coronavirus restrictions on social mixing. But hundreds of people on Sunday brought notes, cards and flowers to the gates of Windsor Castle, 32km west of London, while others laid tributes outside Buckingham Palace in the British capital.
Neil Loughton, founder of the Penny Farthing Club, rode his antique bicycle to the palace gates to pay tribute.
"I think that there are some things that are just important and need to be done . Ninety-nine years of life and more than 70 years of service deserves some recognition," he said.

Philip's funeral is set to take place April 17 at Windsor Castle. Only 30 people will be able to attend under the current coronavirus restrictions in England, but the slimmed-down service is scheduled to be broadcast live on television.
Philip's grandson Prince Harry, who stepped away from royal duties last year and now lives in California, will attend the service along with other members of the royal family, palace officials have said. His wife, Meghan, Duchess of Sussex, is pregnant and has been advised by her doctor not to make the journey.
Royal family members said they appreciated the outpouring of tributes and good wishes from people across Britain and around the world to Philip, who was the queen's consort and support through more than seven decades of marriage.

Edward, 57, said the "extraordinary" tributes meant a lot to the royal family. "It just goes to show, he might have been our father, grandfather, father-in-law, but he meant so much to so many other people."
Andrew, 61, who has largely kept out of the public eye since 2019 amid controversy over his friendship with the late convicted sex offender Jeffrey Epstein, also praised the "absolutely amazing tributes".
