I We are using a Custom object calles US_Counties which includes county name, state, and a list of employee personnel with a max record size of 3,145.
1) Programmatically I want to be able to search the map Collection that stores this info by County name and pull out a list of US Counties objecsts and then based on the Account's Physical state, insert certain personnel into the Account's Account team Object. 
Howvever when I search for the Accont's county name in the Map I get all 3,145 records returned.  Can anyone help me find out what I am doing incorrectly?   

2)  Also how can I use this with a batch script and  avoid the 10000 DML statements Governor Limit?
Thanks
Here is the code:
 

system.debug('<<NUMBER OF QUERIES In TOTAL : '+Limits.getLimitQueries());
        
        //For each account selected go and get the Account Team Mebmers while  updating the account owner.
        List<US_Counties__c> uscs = [Select Name,State_Name__c,Field_Director__c, Work_Group_Leader__c, Primary_Missionary__c from US_Counties__c  ORDER BY State_Name__c, Name Asc];
        Map<String,List<US_Counties__c>> usCounties = new Map<String,List<US_Counties__c>>();
        List<US_Counties__c> all_counties = new List<US_Counties__c>();
        for(US_Counties__c usc : uscs){
            	all_counties.add(usc);
            	usCounties.put(usc.Name,all_counties);
		}
        for(Account a: Accts){
        	system.debug('<<NUMBER OF QUERIES In TOTAL : '+Limits.getLimitQueries());
           	system.debug('<<ACCOUNT>> '+a);
            //Make sure that the Physical Counties are searched on and not Phys state because the returned list size is much less on avg.
            List<US_Counties__c> sampleCty = usCounties.get(a.Physical_County__c);
          	system.debug('<<GET COUNTIES SIZE>> '+sampleCty.size());//displays 3,145 records and not 8 for Orange County
            system.debug('<<GET PHY COUNTY >> '+a.Physical_County__c);
            List<US_Counties__c> countiesFound = new List<US_Counties__c>();
          try{
            	countiesFound = usCounties.get(a.Physical_County__c);
			system.debug('<<GET COUNTIES FOUND>> '+countiesFound);
              	for(US_Counties__c a_county : countiesFound){
                    if(a_county.State_Name__c == a.Physical_State__c){

                        break;
                    }
              	}
