During a memorial service in the Borders, Doddie's children read a poem about him.
Six years after he was diagnosed with motor neurone disease, the former Scotland rugby player passed away.
The sons wore suits similar to their father's for the service at the church.
Timmy Douglas wrote a song called "Requiem for Doddie"
He used to be called a "mad giraffe" for his unique playing style.
His My Name'5 Doddie foundation raised millions of pounds for research and support after he was diagnosed with a rare disease.
He received an Officer of the Order of the British Empire for his services to rugby. He passed away last month.
The memorial service was streamed on Scottish Rugby's website and the audio was relayed to about 1,000 members of the public at the Melrose Rugby Club.
Kathy thanked people before the ceremony for their support after his death.
She said that they have received many messages from all over the world.
They have made me feel comforted.
We appreciate people sharing their memories of Doddie and letting us know they are thinking of us.
The memorial service will allow people to come together and remember Doddie.
Not everyone will be able to make it, but we know you're thinking of us.
He was a rugby player and a farmer.
He said he wanted to preserve the memories he had with the man.
He saiddie had an amazing life. The movie was action packed and full of fun.
He paid tribute to the hope that Doddie was able to give.
"You just don't know what's around the corner, so enjoy life while you can," he said.
The rugby legend was remembered by his former teammate and Scottish Rugby chairman.
They talked about how he centred his life around his family, his playful antics on and off the rugby pitch, and his determination to help people with motor neurone disease.
One of the best loved icons of the game of rugby is Weir.
He said that he had moved mountains, galvanised government, inspired nations and set in motion a crusade that would only end when a cure was found for the disease.
Mr Jeffrey said that the impact on the rugby community in Scotland and the rest of the British Isles was beyond what was thought.
He said that his jokes became more embarrassing, his humor became more childish, his prank became more outrageous, and his tartan suits were more outrageous.
He said that the success of the foundation was down to him being dogged, determined and bloody-minded.
He said how proud he was of Kathy and his sons.
