Delagrammatikas
I have no idea on this one. Sounds kind of Greek, but I don't know. I found out "dela" and it's variants "deles, delas, etc" mean "son of" in Portuguese but I really have no idea if they're related.
I hope somebody out there knows this name's origin and meaning. I'm itching to find out. I will keep looking regardless and will post a follow up should I discover anything new. Thanks for your time.
