I did some research today. I like to know the reasons for things and the meanings behind them as well. I knew Miles meant "soldier" because that is my youngest son's name. Very appropriate and meaningful name for Quaritch, as the lead soldier for the RDA. I got to wondering about the rest of the humans and came up with this:
Jake: short for Jacob, Hebrew name meaning "supplanter" (takes the place of another)
Grace: one of the virtues, meaning good will (she smokes and drinks)
Thomas: Greek for "a twin" (rather obvious)
Norman: multiple meanings; Northman, Thor mind, Thor courage
Parker: game keeper or park keeper (he's in charge of Pandora)
Just goes to show you, Cameron knows what he is doing AND he has a great sense of humor.
