Leading the tribute were Robyn’s devastated parents, Danielle Falconer and Barry Knox, who also revealed they were expecting twin boys.
Posting on Facebook, a friend of the couple said: “An amazing turnout tonight for such a special little girl, Barry and Danielle are two of the strongest people I know.”
There had been some criticism of the decision to hold a balloon release from people concerned about the impact of such events on the environment.
However, there has also been an outpouring of support for the family as they come to terms with their grief.
Danielle posted on social media: “Just to make them all aware there will be a bench, a tree and a mural too.
“The balloons are just happening first.”
She added: “Thank you so much to everyone who joined us tonight.”
