That's a great suggestion, Christine! Including a location would be helpful in many WikiTree reports. The current location fields do not have separate fields for state/province or country, so it may not be possible to do the sorting you suggest. For example, if someone lists only "PA" in the location field, and someone else lists "Pennsylvania", and a third person lists "Penna., USA", I'm not sure how it would sort. Add to that complication someone listing "Luzerne, PA", "Luzerne Co., Pennsylvania, United States", "Plains, Luzerne, PA, United States of America", or "Pennsylvania, Luzerne County, Plains", and the many other possible variations. This could be a difficult problem to solve, but I leave that to other experts to decide.
Though we don't have standard location formats yet, I know options to do this are being discussed.
