pull value from specific row in a table (MySQL query)???

i'm having a problem with something that i feel should be fairly easy to do. say i had the following query that creates a list of names and ages of people in the state of texas (sorted alphabetically):

      <?php
      mysql_select_db($database_somedatabase, $somedatabase);
$query_findPeople_rs = "SELECT firstname, age FROM people WHERE state = 'texas' ORDER BY firstname ASC";
$findPeople_rs = mysql_query($query_findPeople_rs, $thesilentcritic) or die(mysql_error());
$row_findPeople_rs = mysql_fetch_assoc($findPeople_rs);
$totalRows_findPeople_rs = mysql_num_rows($findPeople_rs);
?>

So let's say this pulls the following entries (assume all are from texas):
Adam            32
Bob               28
Dave             29
Jim               43
Jim               26
Mike             30
Phil               54
Steve            22
Steve            36

i check the number of rows by:
<?php

$counter = mysql_num_rows($findPeople);

?>

This would set $counter to the number 9.
Now my question is, how would i store the first name of the person in the 9th row (Steve) as the variable $name

<?php
$name = ?
?>
