- READ MORE: Biden pays tribute to late son Beau on Memorial Day
President Joe Biden and his family are honoring his late son Beau Biden on the nine year anniversary of his death.
The president, wife Jill, his son Hunter and other Biden family members walked through Beau's gravesite after attending a private ceremony to mark his passing at St. Joseph on the Brandywine Roman Catholic Church in Wilmington, Delaware.
Hunter's daughters Naomi Biden and her husband Peter and Finnegan Biden were spotted walking together in the cemetery. Joe's other grandchildren Natalie, Hunter, Maisy, and young Beau were also among the group and first daughter Ashley and first sister Valerie flanked the pack.
Naomi's appearance at the gravesite comes as speculation swirls around whether she might be pregnant, making Joe a great grandfather by the November election.
The eldest Biden grandchild, 30, has not formally announced a pregnancy but it was ‘the talk of the state dinner’ last week, according to sources in the room and she's been wearing loose-fitting clothing in recent weeks.

Peter Neal and Naomi Biden have been married two years. She's seen here at the State Dinner last week during which speculation swirled around a possible baby bump
On Thursday, Naomi was wearing a black peacoat that cinched at the waist and flowed out, which could creatively hide a baby bump.
Her father Hunter is due in federal court on Monday for the start of his highly-anticipated gun crimes trial that is casting a shadow over Joe's re-election campaign.
Hunter has a separate federal trial on tax crimes in California that will kick off in September, just weeks before the general election.
Beau Biden struggled and eventually succumbed to brain cancer caused by his time serving in the military.
On Monday, the president paid tribute to Beau and laid a wreath at the Tomb of the Unknown Soldier to commemorate Memorial Day.
Biden reflected on the loss of his own son Beau as he delivered remarks honoring military members at the auditorium at Arlington National Cemetery.
'I know how hard it can be. It brings you back to the exact moment you got that phone call, heard that knock on the door, or held the hand when the last breath was taken.
'I know, it hurts.
'This week marks nine years since I lost my son, beau. Our losses are not the same. He didn't perish in the battlefield. He was a cancer victim next to being a burn pit.
Biden said he remembers Beau's pride in his sense of 'duty.'

'That was the code of my son lived by and the creed you all lived by,' he said referencing the veterans in the audience.
'The creed generations of service members have followed into battle on the grounds around us by fallen heroes from every major conflict in history.
'To defend our Independence, to preserve our union, to defeat fascism, build powerful alliances, forge the fires of two world wars.

On Sunday night, Joe Biden stopped by the home of Hallie Biden (Beau's widow and Hunter's ex-girlfriend).
The visit comes just a week before she is scheduled to testify in Hunter's trial.
Biden spent about 15 minutes at her home in Wilmington, Delaware. His motorcade stopped there in route to the Delaware National Guard Station, where Biden would lift off on Marine One to return to the White House.
White House spokesman Andrew Bates said the president didn't discuss the trial with Hallie Biden during the visit.
'No,' he replied. 'He visited her because of the approaching 9th anniversary of Beau's passing.'

In addition to Hallie Biden, Hunter's ex-wife Kathleen Buhle and his ex-girlfriend Zoe Kestan will also testify in the trial, where Hunter faces three charges related to illegal possession of a gun.
If convicted, he faces up to 25 years in prison. He has pleaded not guilty.
