Mrs Arnold said Wendy had been doing real estate for a number of years and had only been joined by her daughter several months ago after she returned to the workforce to provide for her girls, aged between 3 and 19.
"Please help us achieve our goal. This is an exceptional family who could benefit from a helping hand," Ms Arnold said.
"This page has been set up to help assist the girls with future educational costs enabling them to achieve their future goals and to show that whilst their mother and grandmother may have gone they are not forgotten and much loved."
