Former US president George HW Bush's family has taken centre stage at his funeral at a Houston church, with grandsons who knew him as "Gampy" serving as honorary pallbearers and granddaughters reading from the Bible.
Bush, the 41st US president, died last week in Texas at age 94.
His remains were flown to Texas on Wednesday evening after a state funeral at Washington's National Cathedral which was attended by US President Donald Trump, the four living former US presidents, and foreign leaders.
Thursday's service began at St Martin's Episcopal Church, where Bush worshipped for more than 50 years, with more than 1000 attendees singing America the Beautiful.
Bush's flag-draped casket was carried in soon after.
George P Bush, son of former Florida governor Jeb Bush and one of the former president's 17 grandchildren, reminisced about fly fishing and sharing Blue Bell Creameries ice cream, a well-known Texas brand, as a child with the man he called "Gampy".
James Baker, who served as Bush's secretary of state and was a longtime friend, eulogised the former president as a peacemaker and "a truly beautiful human being".
"He was not considered a skilled speaker, but his deeds were quite eloquent and he demonstrated their eloquence by carving them into the hard granite of history," Baker said, his voice cracking at moments.
Mourners laughed as Baker recalled how Bush would let him know a conversation was over: "'Baker, if you're so smart, why am I president and you're not?'"
Country music star Reba McEntire was among the musical performers at the service.
Following the funeral at St Martin's, a train was to carry Bush's remains about 130km northwest to College Station, Texas, where he will be laid to rest at his presidential library.
The train is a Union Pacific Corp locomotive, numbered 4141 and bearing the name George Bush 41 on the side; it has been in service since 2005.
Bush, who narrowly escaped death as a naval aviator after he was shot down by Japanese forces over the Pacific Ocean in World War II, will be buried with military honours, including a flyover by 21 aircraft from the US Navy.
Bush was president from 1989 to 1993, navigating the collapse of the Soviet Union and expelling former Iraqi President Saddam Hussein's forces from oil-rich Kuwait.
He supported the passage of the American with Disabilities Act, a major civil rights law protecting disabled people from discrimination.
A patrician figure, Bush was voted out of office in part for failing to connect with ordinary Americans during an economic recession.
