The statement "Ages.Insert("family name",Insert("name",23));" doesn't
work. So, how is it possible to do something like this in C++:

map<string, map<string,int>> ages;
ages["family name"]["name"] = 23;

But this does not look like a hash of hashes. Rather it is a hash of
StringxString. If so, then you could make a record type with two string
fields and build a hash over it, or alternatively, pack two strings into
one using some delimiter character. To construct such keys you could write
a helper function:

type Key_Type is new String;
function Key (First_Name, Second_Name : String) return Key_Type;
