A short sentence made long

See if you can figure out what this means:

At some indefinite point in time on the surface of a measured or measurable period during which an action, process, or condition exists or continues, in a portion of the earth’s solid surface distinguishable by boundaries or ownership at or to a considerable distance in space, at or to a considerable distance in space from this or that place, occupied a home a female member of a royal family, especially a daughter or granddaughter of a sovereign.

Note: “at or to a considerable distance in space” is supposed to be repeated. 😉
