The internet has saved you the trouble of worrying about whether or not Codsworth will be able to call your name in Fallout 4.
Codsworth, the robot companion/housekeeper in Fallout 4, can call you by name - but only if your name falls within the 1000 ones Bethesda recorded.
You don't want to commit to a name if it doesn't end up being used, right? Thankfully, dataminers on Reddit came to the rescue with a full list of all available names, male and female.
You can see the list through here, Control+F-ready.
