Forum:Another connection?

It says on the wiki that Eridan's last name, Ampora, is a reference to an ancient container called an amphora (used for holding liquids). I noticed that Feferi's last name, Peixes, is also similar to an ancient container called a pyxis (a box with a separate lid, usually used to hold small personal items). Do you guys think this is a legitimate connection, or am I just imagining this?
