Welcome to the forums!
To track their name, you’ll need a way to collect that info before they visit those pages (it’s possible after but a little trickier). As you suggested yourself, Memberstack is one way of doing that.
Another way is if you ask users for their names as soon as they land on the site and then store that somewhere. Then, as they visit certain pages, you can either make a note of those pages against their name or send their name to Google Analytics along with each “page view”. GA should be able to tell you the pages that were viewed along with the names.
