Forgetting names is not a defect of memory: a name is an arbitrary label with nothing to attach it to, and arbitrary material is exactly what brains are worst at.

For the most part, it’s like these names are just utterly arbitrary, so you have no thing to latch on to. It’s not really a thing that our brain does very well to learn meaningless, arbitrary stuff. So what you need to do is build connections somehow, visualize a connection, and sometimes it’s obvious or sometimes it’s not.
