class MyClass : public OtherClass{
private:
    static vector< pair<string, array<double, 9> > > myVector;
public:
    MyClass(void);
    ~MyClass(void);
};
vector< pair<string, array<double, 9> > > MyClass::myVector;


and in the actual usage:

array<double, 9>  aNumericData =  { 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0 };
sName = temp.GetName();
myVector.push_back(make_pair(sName, aNumericData));
