I "Googled" the word "enderd. Here is one Quote on the word:

which does,however,believe in the necessity of Baptism,though I agree that if one died after choosing baptism,or is "Enderd",from Baptism, they can still...."
So,in this context,has something to do with religion. I also saw a reference to the game,"Dungeons and Dragons",but don't think it would apply to your entry. Also,

their tuition.
