        template<class Container>
        class ProxyCont {
                Container & container;
        public:
                myCont(Container & c) : container(c) {}
                void push_back(FamilyPair::value & v) {
                        container.push_back(v.first);
                }
        };
        
        std::vector<string> names;
        ProxyCont proxy(names);
        std::copy(family.begin(), family.end(), back_inserter(proxy));


Something likt this would work. The naming sucks...
