Surnames that Codsworth supports

I was playing fallout 4. The first round I named my character ‘John The Duvahkiin’ (I just moved to Fallout from ES) and Codsworth called me ‘Sir’. The second time I named my character ‘Alex Johnson’ and Codsworth called me ‘Mr. Johnson’. I was wondering if there is any other surnames like this that when you choose Codsworth can call you by them.

Is there any other options like this in game? I didn’t know about this and accidentally discovered it.


There is a list of all names (Given names and Surnames)* that Codsworth recognises, without using additional mods.

They are, however not separated, merely ordered alphabetically. My bet is that names that are put in the “first name slot” and “last name slot” will determine whether or not he calls you “Adam”, or “Mr/Mrs. Adams”.

Additionally, I don’t believe that there is a “middle name slot” that is recognised, and could potentially throw the whole thing out, resulting in Codsworth simply referring to you as “Sir” or “Ma’am”, and determiners like “the” would be a cause of this.
