Gometra
Ulva & Gometra, and, on Mull, is the Ulva Primary School
Both islands have been on the market at the time of writing (2017), and I'm unclear if they've yet sold. There are small houses on Gometra, including a one-time teacher's house, which are available for accommodation. Ulva also has some accommodation available.
There are no longer schools on either Mull or Gometra, and the Ulva Primary School is actually located over the straits on Mull. A lack of students has made the school's future uncertain, and a recent fight occurred to keep it open. A small environmentally friendly settlement has just been completed nearby, and there seem to be plans for more housing development which may keep the school more secure - although unless planned sensitively there's a high risk of it damaging the amenity and environment of that part of Mull.

Map UO3 below shows Ulva and its smaller neighbour Gometra.
The two are attached by a bridge, which can be seen in a photo below. In Macquarie's time, Gometra was in separate ownership, as it still is. When Macquarie was born, Ulva was in two ownerships, one was that of the clan chieftain Lauchlan Macquarrie, the other of a fellow called John Macquarie. Today Ulva is is a single ownership.
The bridge between Gometra and Ulva can be raised to allow a larger boat to gain access. As you can see in the two photos below, the area between Ulva and Gometra is influenced a lot by the tide - quite clearly a boat of any size would have to enter on the full tide, which would be why the bridge needs to be raised to allow it to pass.
The tide looks as though it could be very dangerous - be careful, and don't get caught on the rocks!
Each owner has a large house on their respective islands. That on Ulva, at least, is a modern construction. Old Lauchlan Macquarrie's house, visited by that self-servingly elitist snob, intellectually superior, irascible old fart and poseur Samuel Johnson and his toadying biographer James Boswell, was apparently not quite up to London-based intellectuals' pretensions, let alone ours of the 21st Century!
The "he" to whom Boswell refers below is, of course, Johnson. Note Johnson's reference to Macquarrie's house as a "hut", because his definition of a gentleman's house has one storey over another, which Macquarrie's house obviously lacked. Mind you, when it suited him he would allow for "... huts, or dwellings, of only one story, inhabited by gentlemen, which have walls cemented with mortar, glass windows, and boarded floors ...". You will note below that Macquarrie's "hut" didn't meet the criterion I've underlined, and Boswell adds a comment regarding the glass windows!
