First, go back to the original GFCI and try reseting it. If something plugged in there won't work (and you've checked the circuit breaker), you have some sleuthing to do. Of course, you're turning the breaker off when you're messing with the wiring and back on when testing.

First thing, is to look carefully at the two receptacles you have replaced. Make sure that they are wired correctly (black to the brass-colored screw, white to the silver-colored screw, ground (bare or green) to the green screw. Make sure that the white/silver terminals/wire are not touching any metal or the bare ground wire when you put it back in the box.

If it still doesn't work, go back to the original remaining GFCI. It will have two terminals marked something like LINE (which goes to the breaker) and LOAD (which feeds those other bathrooms). Disconnect the LOAD side and see if that particular one works. If not it may have failed (at least you should have a spare, again being careful to connect things to the right terminals and no white/neutral touching any bare metal or the bare metal.

If it does work, then one of your other receptacles likely has four wires (plus the ground) going to it. Take that one and disconnect one set of wires from it. Try it. If not disconnect those and connect the other. If that receptacle works in either one of these configurations, you know it is in the far one.
