Yesterday evening saw up to one hundred people take to the streets for the march which started in Cushlawn Park and finished in Bohernabreena.
William Maughan and girlfriend Anna were last seen in April 2015 and their distressed family members believe the pair have been murdered.
The Maughan family has continually campaigned for justice in relation to the disappearance and to try and locate the bodies of the couple.
In an apparent warning to the family to keep quiet, the grave of their other son Michael Bobby, who passed away from meningitis in 2008, was vandalised last week.
William and Bobby’s parents Joe and Helen Maughan say they will not be silenced or intimidated in their quest to find out what happened to the missing couple.
Last night their friends and neighbours who came out to march carried white and yellow balloons to symbolise peace and justice.
Addressing the large crowd Joe Maughan urged anyone with information “do the right thing” and contact the gardai while Helen reiterated the families stance. “We are not going to back down, why should we back down,” she said.
William Maughan and Anna Varslavane were last seen alive on Tuesday April 14 in the Gormanston area of Co Meath.
