Who is Ilana & her crew? Who do they work for? Who do they represent?

It's obvious that Ilana and Ricardus (Richard) are part of the same group or working for the same people whether it's Jacob, Hanso Foundation or some other group that has never been exposed but obviously from long ago because Ilana asks for Ricardus which is the Latin version of Richard. I just thought of something, remember when Juliette,& the gang were going through the flashes and they came upon 1950-something, I believe. The two soldiers that caught them were speaking Latin and Juliette spoke as well, so what the heck is going on??? lol! I'd like to know what you guys think of this?
