I don't think that this would be a good name for an American kid. I mean, look at it! It says trees, plural form of tree. That would be the kid that gets beaten up every day.

Trees is a short form of Theresia, rather than a diminutive (if it were a diminutive, it would have the diminutive suffix -je). Also, this name is also used in Limburgish as a short form for Theresia. [noted -ed]
