Family Tree

[Farnaz]

Hi all!
I'm writing a "family tree"program. there's a function in my class Node which is named SON. it gets 2 strings as arguments (they represent the name of the son and the father to be related respectively). I've got a problem here. if you look at the code below:

class Node
{
    Node *father;
    Node *son;
    string name;
    vector<Node *> kid;


void ADD(string s)
	{
		Node *n= new Node;
		n->name=s;
		nom.push_back(n);
	}

void SON(string s, string f)
	{
		for(int i=0 ; i<nom.size() ; i++)
			{
				if(nom[i]->name==f)
					father=nom[i];
				if (nom[i]->name==s)
					son=nom[i];
			}
		father->kid.push_back(son);
		son->father=father;


	}
};

Does it make sense to do so? doesn't function SON, mix up the father and son with the one in the outer scope?
