You could look at the meanings of names and come up with a name that way. And Hyur midlander naming conventions are pretty much like English names. First names are British/Anglo saxon/Celitc and surnames are like a description of them (job, where they're from, some physical feature, etc.). Highlanders are pretty much the same, but more Germanic.

So if you still use Terin you could come up with a surname that describes the character you're going to make in some way. You could even just come up with some little back story or something to help you come up with one (don't need to go full RP or anything), it's actually pretty fun to do.
