If you just want to see how many names are associated with that regiment, use the now-working NPS link and enter the variables for the 30th Miss. Regiment. You can search for specific names or (by far the better option) list all names:

Of course you can order any of these service files using the link at the top of this page. You'll see it inside the rectangle outlined in red.
