I have a VF action butotn on the account record that currently shows the contacts that have that account listed as their primary account.  I would also like to include in the list contacts that have been "related" to that account as well.  Below is my current apex and VF code.

APEX
public with sharing class DisplayContactsmk
{
    ApexPages.StandardController con;
    account ee;
    List<Account>lstaccount = new List<Account>();
    List<contact>lstcontacts = new List<contact>();
    public DisplayContactsmk(ApexPages.StandardController controller)
    {
        // employee__c ee=(employee__c)controller.getRecord();
        con=controller;
    }
    public List<contact>getconts()
    {
        ee=(account)con.getRecord();
        lstcontacts.clear();
        accIds.clear();
        lstaccount.clear();
        if(ee.name<>null)
        {
            lstaccount=[select id,name from Account where name=:ee.Name];
        }
        for(Integer i=0;i<lstaccount.size();i++)
        {
            accIds.add(lstaccount[i].Id);
        }
        lstcontacts=[select id,name,lastname, firstname, title, email, rcc_rep__c, tac_rep__c, wac_rep__c, 
                     gc_rep__c,phone,accountId from contact where accountid in:accIds order by lastname];
        return lstcontacts;
    }
    set<string>accIds = new set<string>();
}
