You can give them nicknames in game if that makes it easier. You can also change the pool of names or even the entire dwarven language if you want, it's all text files (at least in the ascii version, not sure about Steam)

Check your resolution and scaling settings if it's literally blurry. If you're not using an integer multiple of your monitor's native resolution, fonts can become hard to read because they don't scale evenly into the pixels available. Sometimes games launch for the first time with weird defaults for resolution, so worth having a look if you haven't already.
