[@Billsomething] Should I make a list or something? Here is just a few words I came up with though they do sound a little strange:

Tetzecochians - From the word [i]tetzotzonqui[/i] meaning "stone worker." (although may refer to Dwarves rather than Goblins) 
Cypactii - Taken from [i]cipactli[/i] meaning "crocodile." 
Hucáthens - Taken from the word [i]huecatlaca[/i] meaning "outsider." (I think?) 
Ahachuayollans - I took this one from [i]Ahachi[/i] meaning "small" and [i]cihuayollo[/i] meaning "coward." 
Mauhcazonians - Took from [i]mauhca[/i] which practically means the same as above. 
Oztycans - from [i]oztoc[/i] meaning "cave" (Had to look this up because I forgot). 
Eazotytcai - from [i]eezo[/i] meaning "full of blood" and [i]tētiōchīuhquētl[/i] which is "death shaman." (had to also look "shaman" up). 

Mind you I'm rusty and I'm not exactly a linguist either.
