If you are looking to locate the whereabouts of the Robins family now, it may be worth contacting a local newspaper in the area they used to live. Many local papers now carry a "lost touch" column for family/friends trying to find each other. If printed, your request could well be seen, either by a family member, or a neighbour who remembers the family and could be able to put you in contact again.
Hope this helps
