I have attempted several variations of this format[1] you recommend and 
continue to produce a broken site; dialog to download 
application/octet-stream from the main servername.com and a 'File not 
found.' from https://servername.com/phpmyadmin.

[1]
location  / {
	try_files $uri $uri/ /index.php?$args;
}

location ^~ /phpmyadmin {
	alias /usr/local/www/phpMyAdmin/;
	index index.php index.html;

location ~ \.php$ {
	fastcgi_pass unix:/var/run/php-fpm.sock;
	fastcgi_param DOCUMENT_ROOT /usr/local/www/phpMyAdmin;
	fastcgi_param SCRIPT_FILENAME /usr/local/www/phpMyAdmin/$1;
	fastcgi_param SCRIPT_FILENAME 
/usr/local/www/site1/wordpress$fastcgi_script_name;
	fastcgi_param PATH_INFO $fastcgi_script_name;
	include fastcgi_params;
   }
}

I eagerly anticipate a working example if and when you can provide one. 
Thank you.
