Looking at [ngrams: angried][1] it seems to have been most popular in the early 1800's.

Looking at [results for those years][2] we find usages such as 

 - "[..] but Ahab had angried God"
 - "Our temperate Sage, though angried at that spirit of contradiction [..]"
 - "[..] seemed very sorry, and desirous of appeasing the angried translator"

and this gives me the impression that "angried" is an old and rare alternative spelling of "angered". Use it at your own peril.

Note that the quote you provided is in *italics* and uttered by a child in a novel which points to it not necessarily reflecting standard usage.

**Edit:**

Since you insist that my assessment of your search link was wrong, let's have a look. 

We have a lot of old texts. Examples:

https://i.sstatic.net/c3ytb.png -- a recent book quoting an old text

https://i.sstatic.net/xCg6W.png -- a recent book quoting an old text

https://i.sstatic.net/PNCia.png -- an old text


There were also some contemporary usages. Examples:

https://i.sstatic.net/CbSJt.png -- used by an unruly five-year-old, in *italics* 

https://i.sstatic.net/MlmsO.png -- person A uses "angried", B corrects her

https://i.sstatic.net/m8pev.png -- a quote in heavy dialect


Apart from these, there were some results which had in common that they 

 1. used the word "angried" once in the whole book
 2. were published through self-publishing services


For instance:

https://i.sstatic.net/4siNO.png -- self-published poetry in archaic-sounding language ([link][3])

https://i.sstatic.net/glpMR.png -- self-published youth thriller ([link][4])


If you insist on these sources being enough for you to use the word "angried" that's completely fine. I would use the common and accepted word "angered" instead.
