CBS News Correspondent Lisa Hughes reports it's a loss their mothers feel every day.
And in response to the incident, the Dunblane mothers waged a successful, two-year campaign to have handguns banned in Britain.
Three of those womenall of whom lost daughterswill participate in the Million Mom March in Washington Sunday. In fact, they have been asked to open the rally, which will call for handgun licensing and registration.
"We're not here to say you've got to ban handguns," said Kareen Turner, one of the Scottish moms. "We're here to say, 'Look at your laws, look at what you're doing. And make a safer place. Make Children safe.'"
And the Dunblane moms won't be the only Scottish voices heard at the rally.
After the Dunblane shootings, songwriter Ted Christopher turned to music, rewriting the lyrics of the Bob Dylan classic "Knocking On Heaven's Door" and recording it with Dunblane students. It went to the top of the charts in Britain.
Sunday, Christopher and his band will perform the song with the American World Children's Choir.
"There are people in the states who recognize that you've got it wrong and want some support," said Christopher. "And I'm willing to support them in that."
Politicians, including First Lady Hillary Clinton, will march in Sunday's event, and entertainers are expected to be among the speakers at the mom rally.
And President Clinton is also expected to make an appearance. Mr. Clinton devoted his weekly radio address to the Million Mom March.
"They're saying, enough is enough. Congress must pass
common-sense gun legislation to protect our children without constraining the rights of legitimate gun owners," Mr. Clinton said.
But the focus of Sunday's event at the National Mall will be on what victims have to say, not politicians. Organizers hope this will discourage partisan politics during the rally.
However, it won't discourage a counter rally from being staged nearby by Second Amendment Sisters, Inc., which is independent of the National Rifle Association, and describes itself as a Dallas-based, "grassroots, self-defense and safety-education advocacy group."
After the mom rally, Donna Dee-Thomases, lead organizer of the event, says mothers around the country will transform their grassroots movement into an organization that will endorse and oppose political candidates, based on their position on gun control.
Alison Crozier and the other Dunblane mothers hope the march will send a message to lawmakers. "When they see the amount of mums and everyone involved... they must take notice," said Crozier. "They've got to."
